Disconnects - Page 2


Disconnects refer to a disconnector, a disconnect switch or an isolator switch is used to ensure that an electrical circuit is completely de-energized for service or maintenance. Found in electrical distribution and industrial application, these switches are crucial as machinery must be disconnected from the source of energy for adjustment or repair. To allow isolation of an apparatus such as circuit breakers, transformers, and transmission lines for maintenance, high-voltage isolation switches are used in electrical substations. The disconnector is usually not intended for normal control of the circuit, but only for safety isolation. Disconnectors can be operated either manually or automatically.
