Influence of operational voltage on switching time of the circuit breakers
This paper refers to the magnetic actuator from vacuum circuit breaker. The actuator is one of the main component with functions for switching, latching and release. Due to the low quality of power supply of actuator, undesirable effects such as the delay during the operation of connecting or disconnecting the circuit breaker can result. As case of study to observe this delay was used a monopolar vacuum circuit breaker with to measure the operating time.
