Sir/Madam,
Due to motor problem, control fluid pump changed over from 1 to 2, but pump-2 was not able to develop pressure due to which 600 MW Turbo generator unit tripped.Later on pump-2 stopped and restarted again pressure started building and later on unit was synchronized.Can any one explain what might me the reason for pump not developing pressure during change over and same pump was developing pressure after restarting again???
Accumulator pressures in oil line are checked and they are fine..please suggest actions to be taken...
