Abstract Low voltage electrical heater fault resulted in high voltage switchboard outgoing feeder leapfrog trip in nuclear power station. The electrical component of the fault heater compartment and the data record from the protection device bring out the fault type and the root cause. The solution scheme prevent from the similar leapfrog trip happening, with the security improving of the safety electrical system in nuclear power station.
