The complete toolbox for testing and analyzing high, medium and low voltage circuit breakers

Total function of circuit breaker test system (time test) is to collect and save the data quality related to circuit breaker (disconector switch, breaker) in offline state at which we can make decision about breakers performance quality based on this data. 

Also this system simulates all related maneuvers on breakers such as: Open, Close, Close-Open, Open-delay-Close, Close-delay-Open and Open-delay-Close-Open. And it extracts electro mechanical data of different parts such as: main and auxiliary contacts, open/ close coils and spring charge engine With these information we can be sure of breaker correct performance and we prepare essential prediction for the future.
