Power Factor / Grading Capacitance Measurement – GIS

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 high voltage breaker bushings should be verified with this measurement. 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. Measuring the capacitance can help detect deterioration in capacitive layers of bushings.
