WebTools. Selectivity, also known as circuit breaker discrimination, is the coordination of overcurrent protection devices so that a fault in the installation is cleared by the protection device located immediately upstream of the fault. The purpose of selectivity is to minimize the impact of a failure on the network. WebCircuit Breaker training teaches students the maintenance, testing and repair of circuit breakers from small molded case circuit breakers all the way up to 15,000-volt air magnetic; oil filled and vacuum circuit breakers. Distribution Systems students learn the different types of generating systems and distribution systems.
