IF XFMR FANS HAVE BEEN OFF FOR AN EXTENDED PERIOD OF TIME AND HIGH OIL TEMPS EXIST, RESTART OF FANS MAY ACTUATE FIRE DELUGE SYSTEM DUE TO HIGH FAN EXHAUST AIR TEMPS. THIS WILL TRIP THE FANS AND OIL PUMPS OFF AGAIN. IF THIS OCCURS THE DELUGE VALVES MUST BE RESET BEFORE XFMR FANS AND PUMPS WILL RESTART.

REDUNDANT INDICATION WHICH WILL VERIFY ALARM:
o RED LIGHT IS ON, LOCATED ON THE UNIT AUX TRANSFORMER ALARM PANEL OPERATOR ACTIONS FOR A VALID ALARM:
o NOTIFY SYSTEM DISPATCHER o VERIFY ALL UNIT AUX TRANSFORMER FANS AND OIL PUMPS ARE OPERATING o VERIFY TRANSFORMER TEMPERATURES NORMAL o CONSIDERATION SHOULD BE GIVEN TO REDUCE ELECTRICAL LOAD DISCUSSION:
THIS ALARM INDICATES A POSSIBLE INSULATION BREAKDOWN INSIDE THE TRANSFORMER. AS THE INSULATION DEGRADES COMBUSTIBLE GAS EVOLVES. THE CAS COLLECTS IN A CHAMBER ON THE TOP OF THE TRANSFORMER. THE AMOUNT OF THIS GAS IS READ ON A GAUGE ON THE TRANSFORMER.
