Product Description
The next device encountered in a substation are the high voltage
power fuses. Depending on the line voltage, they may be up to six
feet long. These fuses stop the flow of current in the event of an
internal fault or short-circuit in the transformer. Overloads due
to faults or short circuits on the distribution side of the
substation are prevented by low voltage protective equipment.
Transmission level circuit breakers or circuit switchers are some
of the last devices found in a substation. They are utilized when
there is a need to remotely switch the incoming or outgoing
transmission circuits in a substation. They also may be used in
place of high voltage power fuses.
