Hi
Due to a lightning strike near our power plant, our 2 turbines tripped. We had several miniature breakers which tripped in a UPS supplying equipment in our 66 kV station which is in open air. In a panel for controlling breakers in the 66 kV station, 2 miniature breakers also tripped.
In an alternator panel, a miniature breaker tripped but could not be reset. After troubleshooting, an auxiliary contactor and a diode module were replaced.
We have lightning poles in our 66 kV Station. The lightning did not strike our 66 kV lines because no protection relays tripped.
It is the first time that we had such an incident.
Any idea what can be done to prevent such incident from happening again? Thanks
