IEEE C57.161-2018 PDF
This guide is applicable to the methods of Dielectric Frequency Response (DFR) of liquid-immersed transformers. The guide includes recommendations for instrumentation, procedures for performing the tests, and techniques for analyzing the data. This guide can be used in 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.
New IEEE Standard – Active. 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.
