A spark gap assembly that includes a first spark gap segment and a second spark gap segment electrically connected in series with the first spark gap segment. The first spark gap includes a first spark gap and a first grading circuit electrically connected in parallel with the first spark gap. The second spark gap segment includes a second spark gap and a second grading circuit electrically connected in parallel with the second spark gap.

Spark gap assembly for overvoltage protection and surge arrester

A disconnector device including an isolator connected between a first terminal and to a second terminal, and a sleeve positioned around the isolator and moveable between an un-extended position prior to the isolator operating and an extended position after the isolator operates, the sleeve being configured to trap debris produced by operation of the isolator.

Disconnector device and overvoltage protection assembly including the same

In one aspect, the application provides an electrical system including a conductor, a ground, an arrester electrically connected to the conductor, and a disconnector assembly electrically connected between the arrester and the ground. The disconnector assembly includes an isolator configured to perform an operating function in response to the occurrence of an event and a housing configured to surround the isolator. The isolator includes a first terminal electrically connected to the arrester by a first wire and a second terminal electrically connected to the ground by a second wire. The housing includes a first opening through which the first terminal extends, a second opening through which the second terminal extends, and a retention mechanism configured to hold the isolator in place relative to the arrester.
