Annual apparatus maintenance testing job: During the testing of the 230kV 54MVA generator step-up unit, Delta recorded a noticeable increase in the power factor measurements on the high-side bushings.

Since these results were approaching 300% of nameplate value and were 150% of previously obtained results, the site requested Delta support the bushing changeout. Delta took advantage of the extended outage of this unit to complete the bushing changeout and vacuum process the oil during the repairs.
