Last night [April 22, 2008] at approximately 4:38 PM MST, the 500/345kV bank in the Four Corners 500kV Switchyard experienced a failure of the transformer banks tertiary winding connections. The cause has not been determined at this time. Crews are currently disconnecting the three single-phase transformers that form this transformer bank. There is one single-phase spare transformer available for service. Oil samples are being collected for analysis. The transformers will be Dobled and SFRA tested sometime this evening.

If no more than one transformer is damaged, the transformer connections will be reinstalled, and the bank will be returned to service. This disconnecting, testing, reconnecting, and return to service could be completed within three to five days, depending on conditions found during the inspections and testing.

If more than one transformer is damaged, the Moenkopi Line will not be in service until Unit 5 is returned to service, on or about May 28th. The Moenkopi line can carry all of the 755 MW output of Unit 5.
