The Mitigation of arc-flash incident energy is important to increase safety. One method is to reduce the duration of the arc flash by using protective relays to sense an arc-flash fault. This method requires a supply-side switching device that will respond to the protective relaying fast enough to mitigate the incident energy. In many existing installations, medium-voltage (MV) controllable fuses...
Mitigation of arc flash incident energy is important to increase safety. One method is to reduce the duration of the arc flash by using protective relays to sense an arc flash fault. This method requires a supply-side overcurrent protective device that will respond to the protective relaying fast enough to mitigate the incident energy. In many existing installations, MV transformer primary fuses are...
