ABSTRACT:
A high voltage fault interrupter including a vacuum interrupter having a fixed contact and a movable contact, a trip mechanism module connected to said movable contact, said trip mechanism module monitoring the power line for conditions which call for circuit interruption, a dielectric housing completely enclosing said interrupter and said trip mechanism module, the housing including a flexible dielectric interface, and an actuating and reset module connected to said trip mechanism module through the flexible dielectric interface. The trip mechanism module can include contact position and fault condition indicators within the dielectric housing which are visible externally to indicate the condition of the interrupter. The high voltage interrupter can include a hydraulic interphase trip module which is responsive to fault opening of the vacuum interrupter for providing a hydraulic pulse to a second and third circuit interrupter connected in the same system.
