Fault on a line


Description:
This model is a faulty line. The distance of the fault from the origin is a parameter. CP or PI models are used on each side of the fault according to the time step. If the time step is small enough t... 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
