All you need to know about Switchgear: Working and Types

A generator is a device capable of supplying electrical energy during a power outage, to avoid the discontinuity of daily activities in industry, commerce or at home. There are generators with different electrical and physical configurations, according to their different applications. An electrical generator is a device that converts mechanical energy obtained from an external source into electrical energy as an output. Modern generators work on the principle of electromagnetic induction.

Regardless of the size of your business, investing in a power generator to keep it running in the event of a power outage is always a good decision. In buildings under construction, where the electricity grid has not yet been connected, electric generators are often the only source of energy available to be able to work. Generators also need periodical maintenance. If you need emergency generator maintenance or repairing service, you can buy genuine parts from the best generator spare parts suppliers in UAE  at affordable prices.

Installation of switch gear system

Switchgear is mainly composed of electrical disconnect switches, fuses or circuit breakers, to control and distribute the electrical energy. The installation of the electrical panel is a service that brings countless benefits for companies and industries that decide for this option. With the main objective of bringing automation to the controls, the installation of the electrical switchgear panel by the best electric switch gear companies in UAE,  contributes to a better productivity and helps to improve the processes, besides allowing the execution of complex tasks.

All of these commands are carried out safely with the installation of the panel since their placement is made to avoid short circuits that can cause serious accidents and also compromise the production and tasks of the site. The installation of the switchgear panel also ensures that the machines of a company or industry are correctly fed with electrical energy, also contributing to the production having a higher yield. With agility, competence and competitive prices as the main focus of service, ATS Electrical Generator TR.LLC, one of the leading switch gear manufacturing companies in UAE, offers its customers pre-sales service with the visit of an engineer and after-sales by telephone contact or engineer return when necessary. In addition, its services have a warranty.

What are the types of Types of switchgears?

Earlier, switchgears were introduced only in power station applications. The knife type switches installed on the panels were made of asbestos or marble. As the technology grows, switchgears become an essential part in electrical field. However, as technology grows, the knife type switches have become more advanced. Now the switchgear panels have integrated circuit breakers to prevent shock.

As part of the technological evolution, switchgears are now installed on residential emergency generators, besides industries and corporate sectors, such as hospitals, aerospace facilities, data centres and other industries that require continuous power. The types of switchgears made by electrical switch gear companies in UAE are Low voltage switchgear, Medium voltage switchgear and High voltage switchgear.

What elements make up the switchgear panel?

It is important that you know that every panel installed must have two mandatory and extremely important devices. They are Power Control Switch (it is the switch that is located next to the General Control and Protection Panel), and General Control and Protection Panel (it is the box where all the safety, protection and distribution devices of the electrical installation are located). Automatic General Switch is responsible for protecting the system from overloads and short circuits. The Differential Switch is of great importance within the switchgear panel since it acts by disconnecting the electrical installation in the event of an earth leakage.

In this way it protects you against indirect contacts. Small Automatic Switches have the function of protecting the conductors that make up the different independent circuits against overloads and short circuits. The number of PIAs installed will depend on the facilities and devices you have. Surge Protector mainly prevents your electrical devices from being damaged by a power surge regardless of the origin. In case of emergency support or sudden break down, it is recommended to hire professional generator Maintenance Company in UAE at affordable prices.

Why use an automatic transfer switch?

Installing a generator ATS panel means that the generator does not need to be switched on manually once the mains power supply has failed. They are must when essential electrical hardware needs to have a continuing power supply and a back-up generator is the only option. Residential properties with a domestic power supply and a backup generator can also benefit from generator change over switches to keep the lights on when there is a power cut. This is a very good option for isolated properties. Modern range and higher specification ATS panels made by the electrical switch gear companies in UAE use the latest microprocessor control modules to enhance and provide maximum functionality.

Conclusion

The generators are used as emergency mechanisms to guarantee the electricity supply in the event of a cut in the main electrical network, either due to a failure, accident or as a consequence of some type of natural disaster. In this sense, the ATS are essential. It is a system that detects when there is an interruption in the electricity supply and that automatically activates the generator set. In this way, the user does not have to be aware of connecting the device manually, but it is directly activated thanks to the ATS. Likewise, the ATS detects again when the main electrical network has been re-established and shuts down the equipment.

How to Extend Life of Your Switch Gears?

switchgear-manufacturing companies in UAE

Switchgear is an electrical tool used to control the electricity flow into an electrical system. The devices and hidden equipment are used for the same purposes, to prevent overloads and short circuits and to de-energize circuits for testing and maintenance. Circuit breakers and fuses, which stop the power flow from getting too high, and power switches, which exchange electricity sources from primary to a secondary source, for example, access to power generation when power is shut down, are the most common types of switchgear.

The switch must serve as a transmission, formation, and division of the normal load current. Furthermore, the defect current must be visible, which depends on the application, is used for sensing devices such as current transformers, future transformers, and various types of relays. In addition, there must be calculation, control, and data, using innumerable devices for switching purposes.

It may include disconnectors, current transformers, potential transformers, measuring devices, switches, fuses, MCB’s, emergency arresters, isolators, and a variety of systems.

Features of Switchgear

Complete Reliability

The ongoing interconnection trend and rising capability of power plants have given priority to the need for reliable switchgear.

Unsurprisingly, the power system is added to increase reliability. If a fault occurs on any portion of the power grid, the faulted segment of the remaining circuit must be isolated.

Certain Discrimination

If any power system segment has a malfunction, the switchgear needs to be able to differentiate between the damaged section and the safe section.

The defective section should be isolated from the device without affecting the safe segment. This ensures the consistency of delivery.

Quick Functionality

If any aspect of the power system is defaulting, the switching equipment must be worked rapidly so that the short circuit current does not harm generators, transformers, or other equipment.

It can spread to safe sections if the fault is not removed rapidly, thereby endangering the complete system shutdown

Manual Monitoring Provisions

Manual control must be provided for switchgear by switchgear-manufacturing companies in UAE. In the event that the electric (or electronic) control fails, manual control may be used to perform the required operation.

How to Extend the Life of Your Switchgear

Aging switchgear can impact reliability and financial losses negatively on the continuity of services in industrial facilities.

In particular, the protection of workers may be affected. According to Contingency Planning Research, in addition to possible threats to human lives, downtime costs have now been measured in million dollars/hour.

The life span of the switchgear depends mainly on how massive the load is and how many switching cycles are there. The reference to the number of operations is typically made rather than a cycle with the electromechanical switchgear since the aging depends primarily on stress and less on the on and off phase between switching.

Following are some life extension tips to enhance electrical reliability.

Perform Infrared Inspections

Thermal imaging (infrared) is a helpful tool that can be performed while the equipment is energized, but not a replacement for a maintenance program. If performed safely and correctly, loose bus connections can be detected by infrared inspection until they result in a complete or partial outage of equipment. To fix the defined issue, maintenance can be arranged by switchgear-manufacturing companies in UAE. The installation of infrared viewing windows enables infrared inspections to be conducted easily and safely.

Exercise Circuit Breakers Annually

Manually operating circuit breakers once a year is a basic but very precious activity. This guarantees clean contacts and free flow of organizational mechanisms.

Do not ignore the recommended maintenance

Cleaning, inspections, tightening, lubricating and regular exercising of the switchgear are necessary. The Diesel generator suppliers in UAE determine the maintenance frequency by operating conditions. The isolation, conductive materials, and protective equipment shall be degraded at an accelerated pace with moisture and heat combined with dirt, dust, and other environmental contaminants.>

Recondition the Equipment

In-house retrofitting shall be a more intensive repair alternative for circuit breakers if on-site maintenance work does not permit the circuit breaker to comply with tolerances as specified by current industry standards. First, the circuit breaker is assessed against ANSI requirements and then disassembled, cleaned, and inspected completely. Damaged components are reworked or removed and pivot points are refurbished before the reassembly of the circuit interrupter. The reconditioned circuit breaker is checked against ANSI requirements, including the new assemblies.

Keep Strong Records and Pattern Performance

Where maintenance tests are not used to monitor circuit breaker efficiency, deterioration in isolation and moving components could become unknown. Without design tolerance, switchgear components can still be used for a long time. The tracking of test data provides a better picture of the life expectancy of equipment and contributes to the emphasis on repair areas.

Upgrade the Equipment

The developments in circuit breaker designs can no longer be viewed as sustainable alternatives for those with older technology. The switchgear lineup may be substituted to take advantage of advanced technologies. A cheaper option would be to keep the switchgear and bus structure in place and update the current equipment with the new state-of-the-art interrupters.

Outsource Preventive Maintenance Via a Long-Term Service Agreement

All of the required service activities for a distribution system can be carried out by very few electrical maintenance or contracting firms.

A professional electrical engineer may help plant management by selecting a qualified electrical maintenance contractor to establish a maintenance and frequency service agreement.

This means that maintenance is not neglected and uniform working areas are used for the entire period of the contract.

Use Predictive Tools for Maintenance

In order to prevent impending failures, online monitoring tools can also be provided in addition to tendency test data that can be analyzed for the provision of equipment life and maintenance needs.

Online monitoring systems of switchgear-manufacturing companies in UAE work constantly and benefit from the recognition of conditions unable to be observed during one-time inspections.

Perform a short circuit analysis and a time study

If there is no proper shortening rate for switchgear components, the equipment and the surrounding area could be catastrophically damaged. A short circuit analysis determines whether the switchgear is correctly rated. The teamwork analysis will also have to be revised. Coordinated circuit breaker settings can prevent the switchgear from unnecessary interruptions of defects, which a downstream device should have interrupted.

Types Of Switch Gear In Electrical System

Before searching for electrical switch gear companies in UAE, you must get knowledge about this segment. Switchgear is the apparatus used to control, regulate, and turn on/off the electrical circuit in the electrical power system. The examples of switchgear devices are:

  • Circuit breaker
  • Control panel
  • Power switches
  • Fuses
  • Relays
  • Potential and current transformer
  • Isolator
  • Lightning arresters

Electrical switch gear companies in uAE
The switchgear manufacturing companies in UAE produce the best systems for installation at home or commercial buildings. The main power supply of any place consists of the whole switchgear system. It is placed on the low and high voltage side of the transformer. It is majorly used for de-energization of the equipment for maintenance, testing, or fault clearance.

In case of any fault occurring in the power system, there could be a chance of heavy current flowing through the device due to which it has a higher chance to get damaged. This interrupts the services and hence, the line gets interrupted. There are many ways to protect the generators, transformers, lines, and other electrical equipment from automated damage protection devices or simply, switchgear devices.

The automated protective switchgear consists of two parts:

Relay: This comes into operation when the fault occurs in any section of the system

Circuit breaker: The closure of the circuit for disconnection or breaking occurs for the faulty section
The protective switchgear can interrupt the faulty segment and the healthy section continues working in the usual mode without any interruption or damaging any equipment. The generators repairing in Sharjah is done by the experts to deal with any issues in the circuits and there is a complete change in the switchgear by the generator maintenance company in UAE.

Types of Switchgear

Switchgear power systems can differ as per the factors such as system location, power requirement, and the necessary security. There are different types of switchgear power systems with their characteristics and the switch gear manufacturing companies in UAE produce the most effective type of systems for various uses.

There are mainly two types of switchgear:

  • Outdoor type: It is used for voltage over 66 kV. Due to the higher voltage, the building work gets a redundant increase in installation costing due to the large space between the conductor and the huge size of the insulators.
  • Indoor type: It is used for voltage levels below 66 kV. There is no difficulty in providing the building work for the switchgear at optimum costing. The electrical switch gear companies in UAE manufacture indoor switchgear that is metallic and compact. Due to this reason, there is a reduction in the safety clearance for operation and hence, there is a lesser requirement of the area.

There are Gas-Insulated switchgear systems available now that are insulated by the pressurized sulfur hexafluoride gas. There are other types also available, such as vacuum and oil-insulated switchgear and these are used differently for various purposes.

How does switchgear work?

Switchgear includes the electrical disconnect switches, circuit breakers, and fuses for controlling and protecting the isolated electrical equipment. It can de-energize the equipment for allowing the work to be done and clear the faults.

PROS AND CONS OF SWITCH GEAR

Indoor Switchgear Introduction

In general, switchgear is a comprehensive term used for the unit with combinational metering equipment types and a protective control as a whole. There can be various types of devices developed by the switchgear manufacturing companies in UAE that are used in different types of applications. There could be rail traction, motor protection, feeder protection, measurements, and other applications that are done with indoor switchgear. The switchgear installed at the electrical power substation can handle the functions, such as incoming feeder connectivity, switching the capacitor banks, control, and monitoring, measuring voltage and current, storage in a battery, etc.

The switchgear system has a direct linkage to the power supply system. It is placed at the low and high voltage sides of any power transformer. The purpose could be for testing, maintenance, or fault clearing of the equipment. Switchgear can be different as per the voltage levels and economical scope. The indoor switchgear is mainly used for medium voltages and is also termed as Mid-Voltage (MV Switchgear). It is enclosed in the metallic grounded enclosures with voltage levels from 3 – 36 kV (the range of medium voltages). The voltages higher than 36 kV can be employed as high voltages. The majority of the electrical switch gear companies in UAE work for indoor switchgear and we shall be discussing the indoor switchgear options in this article.

Indoor Switchgear Design

In comparison to the outdoor switchgear, the indoor variant mainly has GIS technology (Gas Insulated System) instead of the air-insulated system. GIS applies to the high-cost of lands and the areas with a lot of dust and corrosive environment. The arrangement of switchgear is enclosed in the well-grounded metallic enclosure on all the sides along with the openings aimed at inspection and ventilation. The units are insulated in a gaseous environment. Sulfur Hexafluoride gas (SF6) is preferred in this case for insulation with its dielectric properties. The dielectric strength of SF6 is much higher than that of air (3 times higher). The metallic enclosure provides a safe environment in comparison to the outdoor system.

The metal enclosure has two categories of indoor switchgear in terms of metal partitioning and switching methods:

1) Metal-enclosed indoor switchgear

This switchgear arrangement has the metallic sheets enclosed on all the sides with the primary interrupting equipment and fuses with all the equipment pieces encased in the centralized assembly. The access to the interior of the enclosure is provided by the doors and the removable coverings.

2) Metal Clad Switchgear

This switchgear type has the circuit breakers as the vacuum type and can be withdrawn from the original place. The grounded metallic barriers separately isolate the relaying and metering instruments. The main bus continuous ratings are 1.2 kA, 2 kA, 3 kA, and 4 kA with the voltage levels in the range of 4.76-38 kV.

Generally, all the metallic-clad switch gears are enclosed with metal but all the metal-enclosed do not come in the category of metal-clad switchgear. The advantages of metal-clad switchgear are much more than metal-enclosed switchgear. The metal-clad option can be easily customized as per the requirements and the best switch gear manufacturing companies in UAE could make attempts to do the needful as per the need of the clients. There is a pre-built to a customized range of indoor switchgear available that could be highly beneficial for the different uses.

Benefits of Indoor Switchgear

In comparison to the outdoor switchgear, there are indoor electrical switch gear companies in UAE defining the advantages of indoor switchgear over the other available options. Here are some advantages listed for the indoor switchgear:

  • Lesser space requirements than outdoor systems
  • Lower maintenance and operative costs
  • Higher reliability and safety
  • Secured and consistent
  • Lower operational cost
  • Reduced electrocuting risks due to the grounded metallic enclosures
  • Durable systems
  • Less environmental risk factors

Drawbacks of Indoor Switchgear

Despite having several positive points, the major disadvantage of Indoor switchgear, as mentioned by the tower light suppliers in UAE is that these come with the higher costs of installation. The economic factors play an important role and there is a high cost involved in the installation of the indoor switchers. The outdoor system or the air-insulated system becomes a choice for many for cost-effective choices. However, there are some diesel generator suppliers in UAE giving the most reliable and pocket-friendly solutions for the indoor switchgear.

Indoor switchgear system arrangements are more secured and reliable in comparison to the outdoor ones. However, the cost could be higher but ultimately, it is a better choice. It can even withstand severe weather conditions and works well in every atmosphere. The high voltage levels and economic factors are something to consider for indoor switchgear systems. Rest, all is just perfect with the indoor variant.

7 Reasons why investing in Diesel generator will benefit your business

Diesel Generator Supplier in UAE can give you the different generator options to be installed at home or at commercial locations. It is a requirement for every house or industry to get the Genset installed. It can be your assistance on the power outages and it has to be purchased and repaired from the renowned resources for the best results. People look for generators repairing in Sharjah to regularly service or maintain their generators to make them run properly and even increase their lifespan.

The diesel generator has an electric and diesel-based engine that is capable of generating electrical energy. It is a suitable substitute for electrical power and comes in different models, shapes, and designs. The cost of generators depends on their capacity and manufacturing stats. There are different types of generators available and you must know the different types to make your decision to buy them.

Some safety measures must be considered while making a purchase for the Genset for avoiding any injuries or accidents:

  1. Avoiding enclosed spaces
    Generators emit a huge amount of Carbon Monoxide gas along with other harmful gases. It is dangerous to run any generator in a closed space as CO is a deadly gas and can cause severe injuries. Space, where a generator is kept, must be approx. 20-30 feet away from the house and the point of the exhaust must be away from the residential areas. You must have a detector for excessive carbon monoxide emission to avoid any bad chances.
  2. Cord Placement
    Many accidents occur because people don’t carefully place the power cords. The tripping of cords can give a jerk to plugs and the generator outlet gets damaged. It is important to cover the wires with cable covers or install the warning flags as a signal to prevent people to enter the Genset space.
  3. Portable Gensets care
    Gensets for home are generally portable that can be shifted from one place to the other. You need to be careful about securing the Genset while not in use. It must be kept at a leveled surface to avoid accidental slipping or rolling down the slope. The Genset must not be kept in the general path where injuries can occur with unintended bumping.
  4. Avoid Overloading
    Genset shouldn’t be overloaded as it can overheat the power outlets, damaged diodes, blown fuse, and short-circuiting. It can lead to an accidental fire situation in contact with the combustible elements like LPG, diesel spread, etc. Kutoba suppliers in UAE define the serious consequences that can occur due to overloading and should be avoided to save your generator.
  5. Covering the generator
    Covering your generator is important when not in use. Moisture can spoil the generator and it must be covered to avoid its deterioration. You must not place the generator near stagnant water as it can cause electrical shock. Water seepage can cause rust and short-circuiting. Perkins generator supplier in UAE prefers the installation of the Genset system for its proper working.
  6. Protection from electrocution and shock
    The generator system must never be attached to the electrical mains connection. The electrical damages should be regularly checked for damage and abrasion. Never choose cheap parts for replacement and take the help of the diesel generator supplier in UAE for the best results. The wet conditions should be avoided to get rid of shocks.
  7. Re-fuel and maintenance
    The generator shouldn’t be refueled when the appliance is hot as it can accidentally cause a fire. The machine should be cooled down and there should be refueling done for the generators. The generator repairs in Sharjah are done appropriately and carefully to avoid any disaster. There should be no cigarettes or matchsticks lightened near the generator as it might cause mishap.

Generator Types

Whether you are purchasing a generator for home or offices, you must understand their types.

  • Industrial Diesel Generators: These generators are contractor diesel generators having usage on the construction sites. These need to be sturdy and long-lasting to be used for several hours. Industrial grade generators are generally used for several hours with more power.
  • Cooling system: This type of generators is used for water-cooling and air-cooling systems. Water-based cooling is more durable and used in many places.
  • Domestic Generators: These generators are used for residential usage and come into operation when there is a shortage of power. These are not too huge and have lesser power output in comparison to the other contractor types.
  • Air-cooled diesel generators: These generators depend on the air running through the engine to work for the coolant function. There are not many parts included and this generator has only an air-intake system
  • Water-cooled diesel generators: The cooling effect from these generators is attained through the usage of an additive system. The water flow occurs with the operation of the generator and it doesn’t require much maintenance. The water level needs to be monitored on the regular basis for the working of these generator sets.
