Circuit Breaker Operation Time (Off-Service)
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.
Expert recommends
CIBANO 500 + CB MC2
The safety of the test personnel can be increased when the test is performed with both sides of the breaker safely grounded. The offered solution also decreases interferences and reduces the weight of the required test equipment and minimizes handling effort.
Benefits of this solution
Personnel safety
Decreased interferences
Minimized handling effort
