About Medium Medium Voltage Switchgear

Medium voltage switchgear is a term used to describe a switchgear system that can handle voltages of between 3 and 36 kV. These are available in a variety of forms, including outdoor kinds with metal enclosures, indoor types with metal enclosures, and outdoor types without metal enclosures, among others. The basic requirement of the medium power network is interrupting current whenever there is a fault condition, regardless of the kind of C.B. The mechanism of interruption of this switchgear can be S.F., oil, or vacuum. that the MV switchgear system utilizes.

What is Medium Medium Voltage Switchgear?

Medium voltage switchgear is a group of electrical apparatus encased in a mostly metal construction. A variety of switches, transformers, fuses, and circuit breakers are part of this integrated system. Electrical equipment is better protected, controlled, and separated from one another using electrical panels. Power transmission and distribution networks, as well as medium to large commercial or industrial facilities, frequently contain electrical switchgear. The electrical panel is in charge of ensuring that electrical energy is properly transmitted and distributed to various facilities in addition to safeguarding the electrical equipment inside. Additionally, by keeping the electrical current system at a safe level, medium voltage switchgear offers good protection for electrical workers and equipment.

Essential Features of Switchgear

Complete reliability

The demand for dependable switchgear has increased dramatically as a result of the interconnection trend’s persistence and the capacity of generating stations. This is hardly shocking considering that it was incorporated into the electrical grid to increase reliability. They must work to isolate the affected area from the rest of the circuit when a failure develops in any component of the power system.

Absolutely certain discrimination

The switchgear must be able to distinguish between the faulty segment and the healthy section when a fault arises on any part of the electrical system.
It ought to separate the problematic area from the rest of the system without compromising the functioning area. This will guarantee supply stability.

Quick operation

The switchgear must respond promptly to faults in the power system to prevent short-circuit currents from damaging transformers, generators, and other equipment.
The system could completely shut down if the defect is not fixed right away since it could spread to healthy sections.

Provision for manual control

There must be a manual control option for switchgear. The required procedure can be carried out manually in the event that the electrical (or electronic) control fails.

Voltage classes for electrical switchgear according to ANSI and IEEE standards

The voltage classification of electrical panels is defined by ANSI and IEEE standards as follows:
– Low voltage switchboard: up to 600 volts
– Medium voltage: between 600 volts to 69 kV
– High voltage: between 69 kV to 230 k
The ANSI/IEEE standards also specify ultra-high voltage and ultra-high voltage classes. NEC 2014, on the other hand, increased the threshold for low voltage switchboards to 1000 volts.

Insulation type applied on medium voltage switchboards

The medium voltage switchboard housing’s insulation environment is utilized to shield electrically powered equipment like bushings and bass from unintentional arc movements. The most common type of insulation is air, however, gas and fluid insulation has higher dielectric strength and allows switchboard structures to be smaller. Additionally, liquids provide a cooling benefit.

Air insulation features

The most prevalent and affordable insulation is air. Air also has the lowest dielectric resistance, therefore to survive the impacts of the arc, more sophisticated and physically larger equipment is required.

Gas insulation in medium voltage electrical panel

In comparison to air, gas insulation greatly increases dielectric resistance. Sulfur hexafluoride is the gas that is most frequently utilized as a panel insulator (SF6). A tank filled with pressurized SF6 gas seals off any electrical impacts. This sealed tank’s unique construction makes contractor maintenance unnecessary as well.

Liquid insulation and its properties

Compared to air, liquids have better dielectric characteristics. Additionally, they have the benefit of cooling the system. Although other liquids are utilized to insulate electricity in low voltage switchboards, transformers, and other equipment, we frequently refer to liquid as oil. The chosen liquids must be both environmentally friendly and fireproof.

Mineral oil insulation

It is oil-based insulation that has a track record of success and dependable electrical insulation qualities.

Fluid insulation E200

A polyester-based liquid with low viscosity, no hazardous ingredients, and outstanding thermal, physical, and dielectric properties. The E200 can be used in medium voltage switchboards down to -30 °C because of its low viscosity. It has a flashpoint above 300 degrees Celsius (572 degrees Fahrenheit). As a result, it is inconceivable that its use might result in a fire.

Liquid insulation FR3

Food-grade chemicals and ingestible vegetable oils make up insulation. It doesn’t include any silicon, halogen, oil, or other potentially harmful materials. In soil and water settings, this material is quickly and entirely removed. This liquid proudly passed the testing for liquid toxicity.

Switchgear interrupting devices

Overcurrent protection devices (fuses, circuit breakers) and switches are switching devices since they interrupt the power supply.

Air switch

A switching mechanism that utilizes air as a dielectric is known as an air switch. Compared to oil or vacuum switches, air switches often experience less downtime while being more affordable and offering a dependable method of detaching.

Fuses on MV switchboards

An object that stops current flow is a fuse. By melting a wire or electrical tape that is intended to melt at a specific temperature or time, the current is cut off. The fuses are typically attached to a switch in a medium voltage switchboard to benefit from both overcurrent protection and the capacity to open and close the circuit.

Oil switch

It is a switching mechanism submerged in an oil-filled chamber. Medium voltage switchboards frequently have oil switches installed. It allows for the creation of straightforward oil insulation in the shape of a small chamber.

Vacuum circuit breaker

It is a specific kind of circuit breaker found in a medium voltage switchboard that interrupts both the flow of electricity and the arc inside isolated vacuum bottles. The arc rapidly dissipates and loses energy as a result of the vacuum. Compared to air-type circuit breakers, vacuum circuit breakers can cut substantially greater voltages. Furthermore, they take up a lot less room.

Vacuum fault interrupter

As a circuit breaker and overcurrent protection device, this component replaces the need for separate fuses and switches.

The following shapes can be used to create metal enclosures that are practical, economical, and visually beautiful such as:

Medium Voltage Switchgear: Vital Design Parameters and Uses

This technical article describes many elements of the use of medium voltage switchgear and emphasizes the factors to take into account when choosing the best circuit breakers for various applications. Modern electrical networks depend heavily on medium voltage switchgear, also referred to as MV switchgear, for everything from generating stations to different voltage transmission substations, distribution substations, and load centers.

Important Considerations

Location Considerations

Switchgear is categorized as either indoor switchgear or outdoor switchgear depending on whether it is used for an indoor or outdoor location.

Indoor Switchgear

Indoor switchgear is designed specifically to be installed within buildings or other enclosures, where it is shielded from elements like wind, rain, snow, or unusual dust accumulations, aberrant condensations, ice, and hoary frost.
Typically, indoor switchgear has a metal-clad construction. The switchgear’s numerous parts are organized into compartments and divided by earthed metal walls. As a result, we have compartments for breakers, CT/PT, cable termination, busbars, surge suppressors, LT busbars, instrument panel chambers, etc.
Certain devices may be merged into one compartment depending on the design, for example, some manufacturers may combine CTs, VTs, and the cable termination arrangement in one compartment. Surge suppressors or VTs are positioned in the breaker box in certain other designs (on the truck carriage base).

Outdoor switchgear

Outdoor switchgear is designed to be installed in areas that are exposed to the elements, including rain, dust, and other environmental factors. Depending on the application, these can be mounted on a structure (porcelain-dad switchgear or pole-mounted) or inside a metal enclosure in the form of kiosks for accepting HT connections. The enclosure needs to be weatherproof when installing metal-clad switchgear outside.

Rating Considerations

Circuit breakers are rated at both the maximum operational voltage and the usual rated voltage. The power system to which the circuit breaker is connected shouldn’t go over this maximum operational voltage. The continuous current that a circuit breaker can handle without surpassing the rate of temperature rise is known as the rated current. This is crucial for the major power conducting parts’ insulation’s longevity!
Based on the fault level of the system and location/application, such as whether it is positioned at the generating point/source, far away, or located after other electrical equipment like transformers, the circuit breaker’s breaking capacity and short-time rating should be chosen.

Ambient Considerations

MV switchgear is made to function properly at the ratings listed on the rating plate in a typical environment. An altitude of up to 1000 meters and a temperature of 40°C are considered standard ambient conditions. The switchgear must be derated when these conditions change. For all such high altitude installations, surge suppressor use should also be taken into consideration.

Atmospheric air is utilized in circuit breakers for insulation and cooling. The less dense air at high elevations makes for poor cooling and insulation. Therefore, it is important to think about derating circuit breakers.

System Earthing Considerations

Systems are earthed using both firmly grounded and ineffectively grounded systems. A system that is securely grounded generates ground fault currents that are powerful enough to activate the afflicted feeder’s earth fault relay.

As a result, the right circuit breaker trips, isolating the malfunctioning part of the system without cutting off power to the working part.

Potential transformers with open delta secondary winding used in conjunction with neutral voltage displacement relays or core balance current transformers (often referred to as CBCTs) in conjunction with sensitive earth leakage relays aid in the prompt discovery of these issues.

Seismic Considerations

The idea of seismic withstand criterion was initially developed for machinery utilized in nuclear power generating units. However, massive earthquakes that occurred in many different places of the world caused significant property damage, including severe electrical equipment damage, which drew attention to the necessity for good seismic design of equipment.

Based on the seismic intensity at each of these locations, the various locations are divided into five zones. Seismic testing is used for verification and is carried out on a shaker table, testbed, or other appropriately built test fixture.

Overvoltage Considerations

Surge suppressors, also known as surge arrestors, are used to guard against system overvoltages or over-voltages brought on by a certain kind of switching medium used in electrical equipment like transformers, motors, and capacitor banks.

Surge suppressors using a capacitance-resistance combination and gapless zine oxide surge suppressors are also often employed.

Interrupt and short-circuit ratings

Overcurrent protective device interrupt ratings

The amount of current that an overcurrent protective device, which is commonly a vacuum circuit breaker, can safely interrupt without causing damage to the device itself or the switchgear, is referred to as the interrupt rating. This rating is typically provided on a symmetrical current basis. In medium-voltage overcurrent protection devices, specified parameters such as peak and asymmetrical ratings are also typical. The switchgear assembly itself is not subject to interrupt ratings; rather, they only apply to the actual overcurrent safeguard devices that interrupt the circuit in the event of a fault. For medium-voltage vacuum circuit breakers, typical interrupt values vary from 25 kAIC to 63 kAIC symmetrical. (This rating is frequently referred to as breaking current for IEC equipment.)

Switchgear short-circuit or withstand ratings

The highest amount of current that switchgear can safely sustain (i.e., permit to travel through it) without being damaged is known as the short circuit current rating of the switchgear. This is a measurement of the bracing and support of the busbars, which enables them to pass large currents owing to faults that happen downstream of the switchgear while remaining undamaged and unharmed. The upstream switchgear must have a short circuit current rating greater than the worst-case currents that will be traveling through it to protect against faults in downstream equipment. This makes sure that the equipment upstream that is in the fault current path is protected from harm caused by downstream faults. According to ANSI standards, typical short circuit current (or withstand) ratings range from 25 kA to 63 kA for the 2-second rating and from 40 kA to 101 kA for the 10-cycle rating. This rating is also known as a short-circuit rating, short-circuit withstand rating, or withstand rating when applied to electrical switchgear.

Continuous current

The amount of current that the primary overcurrent protection device and main bus within the switchgear can constantly carry without causing a trip or harming the equipment is known as the continuous current rating of the switchgear. For medium-voltage switchgear, continuous current ratings can commonly range from 600A to 4000A.

Benefits of MV Switchgear

The following advantages are offered to the end user by MV switchgear because it enables the removal of certain components, like the circuit breaker, from the main enclosure without impairing the operation of the remaining components of the switchboard.


Due to the complete customizability of key components within the power system, MV switchgear offers a far more flexible power solution than fixed alternatives. For instance, the end user can select from some manufacturers of protection relays and circuit breakers to design a system specifically for their project needs.

Withdrawable switchgear also enables a special application. One circuit breaker, for instance, can be utilized by switchgear that is equipped with a twin busbar configuration to switch the power supply between the two busbar systems. The breaker can be taken out of one place and put in another to switch from one set of busbars to the other. As a result, only one breaker is required as opposed to two.


Because MV Switchgear handles such high levels of power, systems must be created with user safety in mind. In systems that allow withdrawal, access to the functional unit’s terminals can only be obtained after the functional unit has been taken out of the system. This makes sure that before performing any repair, the terminals are always unplugged from the power source.

Due to the aesthetic separation created when the functional pieces are removed, withdrawable switchgear is frequently preferred. The key benefit of this is that operators can be confident that after the breaker is removed, the system will become voltage-free, allowing mechanically trained repair person to work on live circuits with the least amount of electrical risk possible.

User-Friendly Operation

In addition to providing increased safety, withdrawable switchgear’s effective design makes it simple for operators to reach vital components that need maintenance. Withdrawable parts are mounted on carriers that can be safely and simply removed from and reintegrated into the switchgear. Operators only need to worry about the specific component they are testing because withdrawable switchgear offers a test position where the breaker is physically removed and may be operated independently of the switchgear. In contrast, more caution must be given when using fixed solutions when working on components that are still connected to a live system.

The operation of MV switchgear systems for maintenance is frequently required by organizations since they do not frequently employ dedicated switchgear engineers. Since of the user-friendly interface, withdrawable switchgear is the most responsible design choice in these situations because it lowers the operational risk for non-specialist engineers.

Cost Efficiencies

Although MV switchgear can be more expensive initially than a fixed design, withdrawable systems have a lower lifetime cost because of their flexibility.
A crucial component, like the breaker, needs to be unplugged from the power source to be maintained. However, it is becoming very hard to conveniently schedule planned outages due to the rising demand for a constant power supply. Because maintenance on a breaker may be done with little to no influence on the remainder of the switchgear system, withdrawable systems are a wise choice for mission-critical locations like data centers where downtime can have significant financial consequences.


Electricity is now a need due to the rapid digitalization and the heavy use of electrical and electronic appliances. But in order to avoid accidents or fatalities, electrical distribution must be done in a secure and safe manner. Although maintaining safety at every level of distribution units is crucial, installing safety mechanisms and devices is extremely difficult. One of the most common types of equipment, switchgear, has surface-level characteristics and functions that segment the MV system sufficiently to lessen the degree of circuit outages during electrical work on cables and power plants.
