The essential part of a circuit breaker condition assessment is the ability to compare the latest test results with the previous testing. A Circuit Breaker Analyser stores measured values (main and aux contact timing) and compares them to a manufacturer’s limits. Also, a fingerprint obtained in this way can be used at a later stage as a reference during subsequent measurements.
Circuit Breaker Analyzer & Timer (CAT) series are standalone or PC controlled digital instruments for circuit breaker condition assessment. CAT Advanced Series are analysers for circuit breakers with up to 4 breaks per phase
