Transient recovery voltages in vacuum circuit breakers generated by the early-interruption of the inrush current of large motors
Description:The switching of medium voltage electrical motors is typically realized by means of vacuum circuit breakers (VCBs) essentially in view of their elevated number of switching cycles. As known, switching... see more
