Vacuum Circuit breaker (VCB)


Description:
Three main characteristics of VCBs have been taken into account in the implemented model:
1. the chopping current value;
2. the cold withstand voltage characteristic (or cold gap breakdown v... see more

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
