Abstract :
There has been a pressing need for on-line monitoring and diagnostic techniques for HV bushings and current transformers where deterioration often results in catastrophic failure. This paper expands the available information on this topic and presents the technique for the on-line measurement of dielectric power-factor and capacitance using the Doble M4000 insulation analyzer
