Abstract: Dielectric Frequency Response (DFR) test methods of liquid immersed transformers are

discussed in this guide. The guide includes recommendations for instrumentation, procedures for

performing the tests, and techniques for analyzing the data.

This guide describes factors affecting the DFR test moisture estimate including winding

configuration and measurement set-up, cellulose material type, low molecular weight acids, and

background ac/dc noise interference.

This guide is applicable to both field and factory applications. The purpose of this guide is to provide

the user with information that will assist in performing Dielectric Frequency Response

measurements and interpreting the results from these measurements.

Keywords: dielectric frequency response, dissipation factor, IEEE C57.161™, moisture

estimation, oil conductivity
