A stand-alone, microcomputer-driven extra high voltage circuit breaker analyzer, the Vanguard CT-7000 Digital Circuit Breaker Analyzer applies a test voltage of 35 Vdc to each of the contact channels thus allowing an analog to digital converter (A/D) to determine if a close, an open or an insertion resistor was the state of contact.READ MORE >>

The most typical protective devices installed are overload, over current, reverse power, earth fault, differential proportion etc. Injection tests are carried out to check the operation of these protective relays and the breakers. There are two types of injection tests that are normally conducted – primary injection test and secondary injection test. Primary injection test is conducted by injecting the current that is required for the operation of the protective device power through a circuit breaker. The secondary injection test, on the other hand, is conducted when the circuit breaker, though closed is not carrying any current through the main poles.READ MORE >>
A circuit breaker test set can help you effectively test protective devices by measuring the timing and motion of the mechanism. It simulates electrical system conditions and determines if the circuit breaker will respond properly. If you are looking for a good tester, you might be interested in the Doble TDR9000 or the TDR9100 test sets. These testers provide accurate and efficient testing of dynamic timing and mechanism motion of circuit breakers.READ MORE >>
