What are the two primary functions performed by switchgear?

Switchgear primarily serves two essential functions: switching and protection. The switching function involves controlling the flow of electrical power, enabling operators to switch equipment on and off or redirect power as necessary. This capability is vital for maintaining the operation and reliability of electrical systems.

The protection function is designed to safeguard electrical circuits and equipment from faults and overloads. Switchgear disconnects the circuit in the event of a fault, preventing damage to equipment and ensuring safety for personnel. This protective aspect is crucial for minimizing risks associated with electrical failures, such as short circuits or electrical fires.

Both functions work in tandem to enhance the safety and efficiency of electrical distribution systems, making switchgear a critical component in industrial and commercial applications.
