Circuit Breaker Tester

The circuit breaker tester was developed for an international supplier of medium voltage circuit breakers for automated compliance testing and generating test certificates.  The labview software measured contact velocity at several points on the position curve as well as measuring various contact related timing statistics.  The current and voltage measurement utilised closed-loop hall effect techniques and gave good noise free results.  The software also managed pre-cycling of the circuit breaker as well as endurance testing.
