Introduction to HV and LV Switchgear
HV (High – Voltage) and LV (Low – Voltage) switchgear are crucial components in the electrical power system. HV switchgear is used for voltage levels typically above 1kV and is responsible for controlling, protecting, and isolating high – voltage power circuits. It plays a vital role in power transmission and distribution substations, large industrial plants, and power generation facilities.
