Know All About The Features and Classifications of Switch Gears

Switchgear is basically a piece of equipment that is used for switching, controlling, and protecting electrical circuits and components. Switchgear is a combination of electrical switches, circuit breakers, isolators, relays, and fuses. These devices are used to interrupt the current under both normal and abnormal working situations.

All the components of the switchgear are neatly arranged inside a metal container that has been properly earthed. Apart from shielding the load from any danger or harm, the switchgear also keeps the transmission lines and the switchgear safe and secure. The switches used in normal household use air as an insulating medium. However, circuit breakers that work on high current and voltages use special gases, oil, and vacuum for insulation. Some switchgear even use different types of insulators. That said, if you are looking for switchgear manufacturing companies in UAE, then we are there for you.

Features of a switchgear

Here are some of the features of switchgear.

  1. Complete Reliability – one of the most important features of switchgear is reliability. As the safety of the entire power system is based on the switchgear, it must be able to cut off any faulty section promptly and flawlessly.
  2. Proper discrimination – switchgear must be able to detect any faulty parts of the system and isolate them immediately without disrupting the healthy section. If switchgear is unable to do that, chances are the fault will quickly spread to the entire system and disrupt them entirely.
  3. Quick action – fast response is a mandatory and primary requirement of any switchgear. Why? Because a quick cut-off due to any fault will prevent further damage to transformers or generators. If the switchgear is slow, it means it is inefficient and can be quite dangerous.
  4. Manual control – even though the automatic function is a primary feature of any switchgear, there should also be a provision for manual control in case the automatic control fails.

Many electrical switchgear companies in UAE can help you in finding the right switchgear for you.

Classification of a Switchgear

Switchgear can be generically divided into three groups based on the voltage level: low voltage switchgear, medium voltage switchgear, and high voltage switchgear.

1. Low-voltage switchgear (LV)

Low voltage switchgear is used in power electronic circuits that have voltage levels up to 1KV. Air circuit breakers, oil circuit breakers, earth leakage circuit breakers, micro circuit breakers, molded case circuit breakers, switch fuse units, HRC fuses, and other low voltage devices are some of the examples of low voltage devices needed to protect the low voltage systems.

2. Medium voltage electrical system

These include medium voltage electrical systems that operate up to 36 kV. Medium voltage switchgear is used by the systems operating at this specific voltage level. Equipment like minimum oil circuit breakers and bulk oil circuit breakers are examples of medium voltage switchgear. A particular non-toxic, inert, and insulating gas, like SF6, may be employed by medium voltage switchgear in place of oil, vacuum, or another interruption medium. The medium voltage switchgear can be divided into air, vacuum, and gas-insulated switchgear depending on the type of interruption medium utilized. There are many varieties of medium voltage switchgear including metal-enclosed indoor type, metal-enclosed outdoor type, outdoor type medium voltage switchgear without metal casing, etc. based on casing and installation.

3. High voltage Switchgear

High-voltage switchgear is utilized by electrical systems operating at voltages greater than 36 kV. The high-voltage circuit breaker is the primary piece of equipment used in the building of high-voltage switchgear. The high-voltage switchgear usually uses SF6 gas, vacuum, etc. as its interruption medium. High-level voltage systems and devices tend to cause significant arcing while switching, hence careful consideration must be given to their design. These gadgets must have a very high level of reliability. It must be emphasized that high-voltage switchgear switching and tripping activities are seen quite rarely.

Classification of switchgear based on the voltage to be handled

Based on the voltage to be handled, the switchgear can be classified into two categories – outdoor-type switchgear and indoor-type switchgear.

1. Outdoor-type switchgear

Outdoor-type switchgear is used for voltages above 66kV. This is due to the equipment needed by the system, such as transformers, switches, circuit breakers, etc., needing a sizeable surface area and a broad electrical clearance between the conductors at such high magnitude voltages. You cannot install such a device indoors as it can be extremely expensive.

2. Indoor-Type switchgear

Indoor-type switchgear suits voltages below 66kV. This type of switchgear is made using metal clads. All the pieces of equipment in this piece are fitted together to create an earthed metal case. You can easily install them indoors as they are quite compact and budget-friendly.

To sum it up,

Switchgear are an excellent choice for both indoors and outdoors. If you are looking for electrical switch gear companies in UAE, then we at ATS Electrical Generator are there for you.

Common Generator Problems and How to Avoid Them

In order to properly power required equipment, generators must operate smoothly and efficiently. Like all electrical machinery, generators can occasionally malfunction. We must therefore be mindful of the potential problems with generators and get instant help from generator repairing Sharjah.

The information can either assist us in preventing the issue from arising in the first place or, at the very least, alert us to its existence.

Here in this blog we will see what some of the common generator problems are and how to avoid them.

  • Leaks

Leaks are the first issue that might occur with a generator. Although fuel, coolant, or oil leaks may occasionally occur with a generator, the good news is that most of the time they can be avoided by carrying out routine maintenance inspections. You’ll be able to identify these problems, as well as many more, by performing routine inspections on your unit.

Fuel leaks most frequently happen when the base tank is overfilled. This may occur as a result of a problem with the gasoline pump system or merely due to human mistake. To ensure appropriate fueling, it is essential to have a skilled maintenance specialist perform it.

  • Battery Failures

The most frequent problem with generators is battery failure. As batteries get older, they lose capacity and start to produce less and less power. Knowing how long your generator’s battery will last will help you determine when to replace it before it breaks down.

Before using your generator, always check to make sure the batteries, chargers, and any cables and connections leading to and from the battery are in good condition. Wipe and tighten connections frequently, and clean any sulfation accumulation from the battery plates.

  • Low Coolant

It’s possible that simple coolant depletion is the cause of your generator engine’s overheating. The fluid known as coolant distributes heat throughout the engine to prevent freezing or overheating of engine components, keeping your generator at the proper temperature.

The coolant acts to reduce the high temperatures that the generator’s engine generates. The water in the coolant evaporates over time due to repeated exposure to extremely high temperatures, resulting in low levels. Your engine can have the fluids it needs with routine maintenance, which includes fluid level checks.

  • Wet Stacking

When it comes to diesel generators, wet stacking is another type of fluid leak that reduces generator performance. When fluids like oil, unburned fuel, and condensed water accumulate in the exhaust system and leak out as a thick, dark material, it causes this problem.

A moist stacking problem can be resolved by burning off extra fuel. Monitoring exhaust temperatures, adding provisions for load bank testing, and paralleling generators are other ways to avoid wet stacking in the future. This problem typically only affects diesel generators, however it is frequently to blame when a diesel generator fails to operate at rated loads.

What are the fundamentals of medium voltage switchgears?

Switch gears are centralized collection of circuit breakers, switches and fuses to protect isolate and control electrical equipment. These devices are mounted in metal structures. The collection of the circuit protection devices are called as switchgear line up/assembly. Switchgears are found in electric utility transmission and distribution systems and in medium to large-sized industrial and commercial facilities. As of the best electrical switch gear companies in UAE, Al Taqah- ATS Generators’ range of switchgear and safety equipment is supplied by advanced technology and is manufactured by the finest brains.

Working of Switchgears

The circuit protection devices such as circuit breakers, fuses or switches distribute power to various sections of a facility and the electrical loads. The devices protects individuals and facility equipment but limiting the system current flow to safe levels.

Types of Medium- voltage Switchgear

  • Metal-clad switchgear

The device is medium- voltage electrical switchgear in which all the electrical components along with the incoming-outgoing bus, main circuit breaker, and instrumentation are all enclosed n separate metal compartments to provide ruggedness, easy maintenance and safety. The voltage levels of metal-clad switchgears ranges from 5 kV- 38 kV. It can be used in industrial facilities, electrical power generation and power transmission facilities.

  • Gas-insulated switchgear

This type of switchgears has sealed enclosures, filled with insulating gas like SF6 or SF6 with a mixture of other gases. This enclosure facilitates a compact and low profile installation. The gas insulating medium helps to reduce the distance between interrupting components.

  • Metal-enclosed switchgear

This device contains circuit protection devices like circuit breakers, fusible switches, power fuses and control & metering equipment. Metal-enclosed switchgears can be mounted in common compartments unlike metal-clad switchgear. These type of switchgears is used in industrial and commercial facilities where the electrical service is above 480/600V.

  • Vault/subsurface switchgear

This type of switchgears is used for electrical distribution systems of voltage range 15 kV- 38 kV, with the condition of requiring the switch and the accessories should be operated from below-grade location. The locations can be dry or wet. The vault switchgear allows the user to operate the switch manually from above ground and uses vacuum interrupters to isolate faults and protect loads. SF6, sold materials and solid-dielectric-in –air technology is used for insulation.

  • Pad-mounted switchgear

It is designed for underground distribution systems with a voltage range of 5 kV- 38 kV. This type of switchgears has the features of low profile, outdoor rating and tamper resistant construction which make them ideal for feeder sectionalizing, utility distribution and circuit protection applications. The fuses, switches and vacuum interrupters in the switchgear protect isolate faults, loads and minimize outages. Here, insulation includes fluid, SF6, solid-dielectric-in-air technology and old materials.

Switchgear Insulating Media

Insulating media is used to protect energized devises like bus, bushings etc from sudden arc faults. Air is the common insulator nut gas and fluid insulators provide higher dielectric strength and allow the switchgears to be smaller.

Switchgear Interrupting Devices

Switchgear interrupting devices include over current protection devices such as fuse, circuit breaker, switches and interrupt the flow of electricity.

  • Air Switch- It is a switching device which use air as dielectric and provide a visible means of disconnection. They have lower interrupt ratings than vacuum switches and are more economical.
  • Oil Switch- It is a device which is submerged in an oil-filled enclosure. They can be seen in pad-mounted switchgear where the oil insulation allows the construction of a low- profile enclosure.
  • Vacuum Switch- It is an electrical switch where the electricity is interrupted inside the vacuum bottles. The vacuum permits the arc produced to extinguish quickly. This type of switches requires less space and can be applied at higher voltages.
  • Vacuum circuit breaker- Here, in this device, the arc interruption and quenching takes place inside sealed vacuum bottles. The device permits the arc to extinguish quickly and thus reduce the arc energy. They can interrupt higher voltage faults and requires less space.
  • Fuse- This device interrupts excess current flow. It is achieved by the melting of an electrical wire. Fuses are paired with a switch in medium voltage switchgear applications to provide over current protection and give the ability to open and close the circuit.
  • Vacuum fault interrupter- This device functions as a load- break switch and also as an over current protection device to eliminate the need for a separate switch and fuse.

Interrupt Ratings

Interrupt ratings refers to the magnitude of current that a vacuum circuit breaker can safely interrupt without damaging the switchgear. The interrupting ratings for medium- voltage vacuum circuit breakers range from 25 kAIC – 60 kAIC symmetrical.

Short-circuit ratings

The maximum amount of current that the switchgear can withstand without causing equipment damage is called as short circuit current ratings/ withstanding ratings. It measures the support and bracing of the bus bars that allows them to remain intact and no damage when high current is passing due to faults in downstream equipments. For faults, the upstream switchgear must have a excess short- circuit current rating. That means the downstream faults do not damage the upstream equipments which is in the fault current path. The typical short-circuit current ratings range from 25kA to 63 kA symmetrical for the 2-second rating and 40 kA- 101 kA asymmetrical for the 10-cycle rating.

Continuous current

The amount of current that the main bus and over current protection device within the switchgear can carry without damaging the equipment is called as the continuous current rating of switchgear. For medium- voltage switchgear, the continuous current ratings can range from 600A- 4000A.

Medium voltage switch gears have voltage range of 600V- 230 kV and are classified by the maximum voltage it can service.
