Typical Fault Analysis And Operation And Maintenance Countermeasures For Outdoor High Voltage Disconnectors

If one bus side high voltage isolator is heated during double bus connection, the line can be switched to another bus through switching operation. When the bus can be shut down, after the load is transferred, the above high voltage isolator switch heating problem can be checked by power outage. If there is a bypass bus, the load can be transferred to the bypass bus.
