Purpose of Isolators is to ensure that an electrical circuit is completely de-energized in order to conduct the service or maintenance. Isolators are also familiar as isolation switches for isolating the electrical circuits, such switches are often found in electrical power distribution and industrial appliances and other applications, where it is critical that machinery must have its source of driving power removed for adjustment or repair. High-voltage isolation switches are used in electrical substations to allow isolation of
