One of our Generators, in this case a 30 MW unit, was rebuilt this outage season. It is coupled to a steam turbine. We are able to sync unit but trip 7 seconds later from 32 relay. The GV’s open and there is plenty steam, as its sister unit is running like never before. We have had the Shermco guys tell is we have incorrect rotation of PT secondaries. Would really like anyone’s input as to what might be the cause. 32 relay has been tested and verified good twice. AVR, Basler Decs 400, also shows negative MW after sync and power quality metering with wrap CTs place on generator buss also show negative MW. Any ideas ?
