Troubleshooting 5 MW mobile gas turbines  

Summary: 

End users complained of voltage fluctuations from 5 MW mobile gas turbines.  Initial investigations discovered arc marks and corroded connections in the PT bushings.  This type of corrosion is not common across several hundred similar installations used for the past 10 years.  During review of the original damaged PTs engineers postulated that ferroresonance could potentially be a root cause of voltage fluctuations on the original configuration.  During testing, ferroresonant voltage waveforms were captured by a power quality meter at the secondary of the wye PTs feeding the voltage regulator following a breaker close onto unloaded switchgear.  These waveforms were not present during steady state operation nor were they captured during every breaker close operation.  Each of the captured ferroresonant events were accompanied by high speed over voltage spikes that resembled arcing.  This report summarizes the results of an independent, outside review commissioned to further investigate the ferroresonance issue and possible root cause of the arcing damage observed in the PT connections.
