Circuit Breaker Operation Time (Off-Service) – GIS

For measuring GIS operating times we recommend the Current Sensor Measurement (CSM) method. With this method, the ground connections on the grounding switch do not need to be removed and the GIS remains grounded on both sides. The operating time is measured via an inductive current change measurement using the parallel ground connection of the breaker. The current change that is measured through the ground connection is then used to determine the switch response times.

이 솔루션의 이점

Personnel safety

The safety of the test personnel can be increased when the test is performed with both sides of the breaker safely grounded.

Decreased interferences

The CB MC2 connection modules decrease interferences as they are mounted close to the breaking elements with short cables offering minimized cable length for interferences from other live substation elements.

Minimized handling effort

The offered solution reduces overall test equipment weight by eliminating the need for long and heavy high-current cables and their cumbersome handling.

CPX 200

The CPX 200 verifies operation time, synchronicity, and contact circuit breaker contact timing with a single setup. The motor can be supplied with up to 70V AC / 125V DC from the CPX 200.
