Transformer Liquid Power Factor in Mineral Oil - Part 1
At a calculated liquid power factor (four significant figures) of 10.00%, the dissipation factor would be 10.05%. Contamination of the oil by moisture or by other contaminants will increase the liquid power factor. The aging and oxidation of the oil will also elevate liquid power factor values. Therefore, this is an extremely useful test ... Visit website

Transformer Oil Power Factor - Electric power
Dobles literature says that oil with a power factor of 0.3% or less is acceptable for service, 0.5% is considered "doubtful" and should be tested by other means, and 1.0% should be investigated, reconditioned or replaced. Of course, the Doble oil power factor test setup is a field test and not as rigorously standardized as a laboratory test. Visit website

Power factor - Wikipedia
In electrical engineering, the power factor of an AC power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit. Real power is the instantaneous product of voltage and current and represents the capacity of the electricity for performing work. Apparent power is the product of RMS current and voltage.
