IEEE C57.149-2012

This guide is applicable to the measurement of Frequency Response Analysis (FRA) of an oil-immersed power transformer. The guide will include the requirements and specifications for instrumentation, procedures for performing the tests, techniques for analyzing the data, and recommendations for long-term storage of the data and results. 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 making frequency response measurements and interpreting the results from these measurements. It will provide guidance for all current methods employed in taking these measurements.
