Remember! The High Voltage Disconnector Can Only Be Operated In The Closed State.

When high voltage isolator is closed, it can reliably pass normal load current and short-circuit fault current. Because high voltage isolator switch lacks a dedicated arc extinguishing device, hv isolator cannot interrupt load current and short-circuit current. Therefore, hv isolator switch can only be operated on high voltage electrical isolator after the circuit breaker has been disconnected. Operating isolator high voltage with load is strictly prohibited to avoid serious equipment and personal accidents.
