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.
Voltage drives the flow of electrons through a circuit by creating a potential difference. The higher the voltage, the greater the force, and hence the more electrons flowing through the
They protect at different voltage levels. Surge protective devices handle systems at 1000 volts or less, while surge arresters are used above that threshold. An SPD is not a substitute for a
