A Brief Guide to Switchgears

A power surge is the last thing that anyone wants to experience, especially if you run a business. It can put your electrical systems in a havoc.

Each circuit is designed specifically to handle a said amount of electricity. Thus, when the limit of the electricity exceeds, the wiring can overheat, damaging essential components of the electrical system. This is where switchgears come in, to become your saviors. They have been designed for defending the equipment from various types of electrical threats and power surges.

What is a Switchgear?

Switchgear is not limited to a single device. It is quite extensive. But all the devices that fall under the category of a switchgear, plays one major role, i.e. protecting, controlling and isolating power systems.

In the light of this definition, it can be stated that switchgears include devices that regulate a power system or meter it and circuit breakers etc.

A switchgear is one of the most important components, in an electrical surge situation. A good switchgear will trigger, interrupting the flow of electricity to shield the systems from any damage.

There are various examples of a switchgear, i.e. fuses, isplaters, circuit breakers and relays etc.

Types of Switchgears:

Switchgears are classified under three basic types;

  • Low voltage switchgear
  • High voltage switchgear
  • Medium voltage switchgear

●    Low Voltage switchgear:

These switchgears have been designed to help regulate systems till 1KV. Their functionality is required at the low voltage sides of the power distribution transformers. You can get a high quality low voltage switchgear at Eaton Australia easily.

●    High Voltage Switchgear:

This switchgear can manage up to 75 KV of power and a bit more too. These are breakers and are only designed for high voltage usage. They are usually used for safety purposes.

●    Medium Voltage Switchgear:

Systems that manage 1 KV to 75 KV power use medium voltage switchgear. This type exists in systems that have components like motors, generators and distribution and transmission lines.

How does a Switchgear work?

Every type has a different functional process. However, there are some basic operational guidelines that they are built on. They somewhat follow a similar track of procedures.

If an electrical fault or power surge happens, the relay works to shut the trip circuit off and disconnect all the downstream loads. This permits the remaining system of a circuit to continue working without any trouble, while it protects the other vital components from any damage.

Also, it is important to differentiate between a switchgear and a switchboard. They are two completely opposite electrical tools.

Choosing the right Switchgear

Choosing the right switchgear is very important. You have to determine the type of KV power your equipment is managing and then make a pick. Always take expert advice if you are confused.

CONCLUSION

Backing up your electrical systems with high levels of reliable protection is very important. To ensure it, you must invest in high quality switchgears to manage power surges and electrical faults probably.
