THE RELAY WAS REPLACED AND PLANT WAS RESTARTED WITH TR-Nl OUT OF SERVICE FOR FURTHER EVALUATION.

THE CAUSE OF THE TR-Nl AND TR-N2 SUDDEN PRESSURE RELAY OPERATION WAS TRACED TO AN INSTALLED TEST SWITCH WHICH CAUSED MISOPERATION OF THE RELAYS. THE RELAY WAS REPLACED AND PLANT RESTARTED WITH THE SUDDEN PRESSURE RELAY DYPASSEI FOR FURTHER EVALUATION.
