Power Factor / Grading Capacitance Measurement – AIS

Measuring the power factor, or the dissipation factor, also known as the tangent delta (tan δ), provides effective means for verifying the integrity of the insulation condition of circuit breaker components. In particular, the insulation condition of dead tank high voltage breaker bushings should be verified with this measurement. On dead tank breakers this measurement method is used to verify the insulation condition of the bushings by detecting deterioration in capacitive layers. On life tank high voltages breakers this measurement method is used to evaluate the capacitance of grading capacitors. If the measurement is performed outside of mains frequency, interferences from nearby live station components can be filtered out and minimized. Measuring over a range of frequencies provides better insight into the insulation condition.
