Abstract:

To reduce the damage caused by the arc fault occurred in the 6kV auxiliary power system of large thermal power plant,it should adopt a kind of comprehensive management method including improving the highvoltage transformers resistance to short circuit and using IAC switchgear witch bus protection. It analyses the current status of arc protection device which is based on arc sensor.
