Subject: APPS: GE turbine MARK V control

We had three instances when all the three MARK V processors of GE Frame V turbine had rebooted during lightning. It was observed that lightining struck one of the CVTs in the 132 KV yard adjacent to the captive power plant and at the same time all the processors rebooted, leading to the tripping of the turbine.

The earthing of the MARK V is connected to 2 separate earth pits which are nearer to the yards. Also at the same time other Frame V machine of similar capacity and with a similar earthing status (except that they are having separate earth pits) did not have any effect.
