LV and MV Switchgear: Everything You Need to Know

An LV and MV switchgear acts as the main switch regulator for both low and medium voltage power sources.

It is used to control the power supply of industrial and commercial buildings.

The LV and MV switchgear toggles the power source of an electrical circuit or equipment.

It protects delicate electrical controls inside an enclosure.

LV and MV Switchgear

An LV and MV Switchgear from regulates and toggles electrical power systems.

It also protects the power system regulators from dust and other external factors.

These power system regulators include circuit breakers, switches, fuses, and other electrical components.

Anything that regulates or controls a power system is housed inside an LV and MV switchgear.

Switchgear Assembly

An array of LV and MV switchgear makes it assembly. This assembly is important in regulating and protecting a power supply.

A switchgear assembly has two main functions:

  • Power Conduction
  • Control Systems

The power conduction component includes circuit breakers, switches, lightning arrestors, and fuses.

It acts as an emergency safety measure by conducting or interrupting electrical power flow in case of a surge.

Current transformers, protective relays, control panels, and potential transformers comprise the control system component.

It’s used to control, monitor, and protect conductive power components.

Types of Switchgears

Switchgears may be protected by insulation using other substances or a typical open-air isolator.

Its primary use is to house a circuit breaker, the one responsible for controlling the electrical power supply.

Switchgears has three types:

  • High Voltage (HV)
  • Medium Voltage (MV)
  • Low Voltage (LV)

High Voltage (HV)

High Voltage (HV) switchgear control power over 36KV. It prevents a high voltage power surge that normal can hold.

When the voltage is high, the arcing also increases upon transition.

Making use of high-quality materials in making a high voltage regulator is important. The need to contain high power surge is essential to keep it intact.

Medium Voltage (MV)

A Medium Voltage (MV) accommodates a low power surge. It can hold up to 30-60KV of power.

Medium voltage switchgear varies in material type.

It is mainly made of metal designed for indoor and outdoor use.

Low Voltage (LV)

The Low Voltage (LV) can hold power energy of only 1KV.

Unlike the MV and HV, the LV must be used with equipment that requires a power of not more than 1KV.

Safety measures must be observed at all times to prevent accidents.

Industrial Use

LV and MV are widely used in industrial buildings. It protects electrical power sources and isolates them into different outlets.

The distribution of the electrical power supply of an industrial building is controlled by an LV and MV switchgear.

Its use is important for small to medium industrial spaces. It doesn’t only act as a switch but as a protection for an electrical circuit.

It plays a vital role in controlling heavy electrical equipment in facilities that operate using robotics.

Many power plants use LV and MV switchgear to control the distribution of power supply. Its importance in switching specific power lines makes it convenient in case of emergency.

Home Use

The LV and MV switchgear fits perfectly for home use.

Its ability to channel electricity to different equipment best suits its purpose.

For instance, if you have a garage door driven by hydraulics, the LV and MV switchgear can act as a switch.

If you know more about DIY installation of an automated water sprinkler, you can easily connect it to LV and MV switchgear.

By doing so, controlling your automated sprinkler in the garden becomes easier.

This adds to the convenience of toggling your home electrical equipment.

The Heating, Ventilation, and Air Conditioning (HVAC) system of your house must be connected to LV and MV switchgear.

The LV and MV switchgear protects the HVAC system against sudden power fluctuations.

The forced air system relies on the capacity of the LV and MV switchgear to withstand the sudden shift of settings.

Whether it needs cool or warm air, the HVAC functions well when the power supply is well-regulated.

The home lighting system also relies on the LV and MV switchgear. If a sudden surge of electricity fluctuates the mainline, your lighting system will be spared.

The fuse inside the LV and MV switchgear cushions the sudden change in electrical power. This blocks the damaging effects on your lighting system.

Whether choosing between the LV, MV, or HV, having it is important. For modern enterprises controlling power flows and output is important. It can help prevent outages and improve the performance of heavy machines in units.

Protection against sudden power surge prevents damage to your electrical equipment.

LV and MV switchgear protects the relays and circuit breakers from a power surge.

It channels electrical current to its designated outlet. It also protects the wirings and other electrical pathways to avoid overload.

LV and MV switchgear has many uses. It can act as the control panel of a commercial building in maintaining the balance of power supply.

In some cases, the LV and MV switchgear are arranged along with other switchgear. This becomes a switchgear assembly

Factories that manufacture materials using robotics rely on LV and MV switchgear.

Likewise, your HVAC system, automated sprinklers, and hydraulics door on your garage need the LV and MV switchgear.
