Switchgear
OverviewHousingComponentsFunctionsHistoryCircuit breaker typesProtective circuitryClassification
Switchgear for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher. Oil-insulated switchgear presents an oil spill hazard. Switches may be manually operated or have motor drives to allow for remote control.
Low Voltage Switchboards and Switchgear
Where multiple switchboards or panelboards are used in the same electrical room as a conventional distribution system, the integrated design significantly reduces equipment space requirements, as
Low Voltage Switchgear or LV Switchgear
Electrical switchgear rated up to 1kV is defined as low voltage switchgear. LV switchgear includes devices like circuit breakers, switches, electrical isolators, HRC fuses, earth leakage circuit
