In the electric power system, switchgear is an integral part of the electrical hardware. It includes fuses, switches, relays, isolators and circuit breaker that protects it from faulty conditions. Note that each electronic device needs some kind of protection since they can fail anytime if not properly maintained and maintained.
What is Switchgear?
Switchgear is an electrical equipment that transfers high or low voltage of electricity. It switches the active current from lower to higher voltage through a separate circuit, which is safer than direct connection. This happens in case of an electrical failure or breakdown of the power system within the network. The service of switchyard is crucial to ensure optimum electrical protection. Switchyard keeps track of the set-up throughout the whole day, especially at night when there are minimal interruptions in supply and it also monitors fault conditions such as short circuits, breakdowns etc. The aim is to make sure that there is no damage at all to electric equipment during maintenance or repairs due if there were any electrical faults within the setup.
How Do Switchgear Work?
The primary function of a switchgear is to protect an electrical section by isolating it from the faulty part. It does so by closing off the circuit breaker (or in some cases, the cutout) if there is a fault. This prevents damage to machines and equipment, as well as providing uninterrupted power supply for the load.
Types of Switchgear
There are different types of switchgear, differentiated on their voltage levels. The three categories are:
- High Voltage (H.V.) Switchgear
- Medium Voltage (MV) Switchgear
- Low Voltage LV Switchgear Panels
