After having a recent maintenance testing we observed the following C1 test results. The capacitance values are satisfactory but the PF values were increased for some bushings, when compared to Name plate values mentioned in the report.
We also observed change in oil color in the 34.5Kv bushing sight glasses.
My understanding is higher PF indicates the contamination and deterioration of Bushing’s insulating materials.
Would like to understand other's comments based on the test results and what can we do to mitigate this?
