TESTING OF CIRCUIT BREAKERS AND SWITCHES

Circuit breakers are devices that operate as automatic switches, ensuring that the opening or reclosing commands received from the protection system are executed satisfactorily. The disconnect switches are used as safety devices in the de-energizing of circuits, which makes human work safe.

Due to the importance of these elements, periodic tests are essential in order to diagnose possible operational failures, whether related to the opening / closing times or the resistance they offer to the system when they are closed.

In this context, Conprove has developed a line of universal testers that, in addition to carrying out tests at the secondary level (relays, meters, qualimeters, etc.) also carries out tests at the primary level, which involves the possibility of testing circuit breakers and disconnectors. Among the tests made possible, we can highlight the opening / closing tests of po
