Circuit Breaker Operation Time (Off-Service) – AIS

Timing measurements according to IEC 62271-100 are the most common tests on circuit breakers. These tests are used to determine operation time, pole discrepancy or pre-insertion resistor timing. The test uses a resistance or voltage threshold to measure the timing. Methods that allow tests to be performed with grounding on both sides are preferred because of the increased safety of the personnel performing the tests.

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

CPX 200 verifies operation times, synchronicity, and contact timings on circuit breakers in a single setup. The motor can be supplied with up to 70V AC / 125V DC from the CPX 200.
CPXpert allows phase-by-phase or interrupter-by-interrupter comparisons within each phase.
