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.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
