IEEE Guide for the Dielectric Frequency Response Measurement of Bushings
Abstract: Bushings are critical components for power apparatus as their main role is to conduct current at high voltage through a grounded barrier. Statistical studies have shown that bushing defects such as water ingression and partial discharge are among the most important causes for unexpected failures. Dielectric frequency response (DFR), sometimes also known as frequency domain spectroscopy (FDS), which involves measurement of the bushing capacitance and dielectric losses over a frequency range, is an effective method to detect deterioration of bushing insulation. This guide applies to the DFR measurement of various types of bushings either in the field or in the factory except for gas-insulated bushings.
Keywords: dielectric frequency response (DFR), dissipation factor, moisture, frequency domain spectroscopy (FDS), IEEE C57.12.200, OIP bushing, power factor, RIP bushing, RIS bushing, transformer bushing
