Scope

This document specifies the principles, testing instruments, samples, test procedures, and result analysis of the frequency-domain dielectric spectroscopy test for insulating paper (board) and insulating components used in power transformers. This document is applicable to the frequency-domain dielectric spectroscopy test of unused solid insulating materials used in power transformers and solid insulating materials in operation. It can also be used as a reference for the frequency-domain dielectric spectroscopy test of solid insulating materials used in oil-immersed reactors and bushings.
