Switchgear is a general term used to refer to a range of switches, circuit breakers, fuses, etc., which are used in an electric power system to control, regulate and switch the circuit on and off. By controlling the circuit, switchgear protects and isolates electrical equipment from the power supply, enabling testing, maintenance and fault clearing work to be undertaken.
Switchgear has two types of components:
- Power-conducting components: These conduct or interrupt the power flow; such as switches, circuit breakers, fuses, isolators, relays, lightning arrestors, and so on.
- Control systems: These monitor, control and protect the power-conducting components; such as control panels, current transformers, potential transformers, associated circuitry, and so on.
