High Voltage (HT)
Switchgear
A switchgear is used to both de-energize equipment to allow work to be done and to clear faults downstream. High Voltage Switchgears are a combination of electrical disconnect switches, fuses, or circuit breakers used to control, protect, and isolate electrical equipment.
