About This Item

 

Full Description

Scope

This guide is applicable to the detection and location of sources of acoustic emissions (AEs) from partial discharges (PDs) and other sources in power transformers and power reactors. There are descriptions of acoustic instrumentation, test procedures, and interpretation of results.

Purpose

This guide is intended to provide information that may be helpful in planning, installing, and operating acoustic measuring equipment and in meaningful interpretation of resulting data.

Abstract

Revision Standard - Active. The detection and location of acoustic emissions (AEs) from partial discharges (PDs) and other sources in liquid-insulated power transformers and reactors are covered in this guide. A means of associating the relative magnitude and position of PDs and other sources with the acoustic signals obtained by strategically located transducers is provided.
