Turbine load dropped 300 MWe, both Feedpump Lo Suction - -

Pressure Trip Alarms were received. Cause is suspected to be the shorting of the 15VDC Power Supply on the #1 Steam Generator Steam Flow / Feed Flow Recorder while sliding Recorder into the Control Board. The transient was terminated shortly after the short occurred when a fuse blew isolating the short from the instrumentation buss.
