Privacy Policy Although conventional electromechanical circuit breakers have a proven record as effective and reliable devices for circuit protection, emerging power distribution technologies and architectures, such as dc microgrids, require improved interruption performance characteristics (e.g., faster switching speed).
Current flows continuously through the breaker with negligible loss. Upon disconnecting, semiconductor components ignite and current runs via them repeatedly since the current route possesses lower resistance than the arc path. Additionally, the arc will dissipate and semiconductors will block electricity .
The testing of circuit breakers is essential for the reliability, safety, and efficiency of electrical systems. The built-in test switch selects the testing characteristic, drying contacting testing for remote evaluation, and automatic testing stores information in storage for either monthly or annual assessment .
