IEEE Guide for the Detection and Location of Acoustic Emissions from Partial Discharges in Oil-Immersed Power Transformers and Reactors
This guide is applicable to the detection and location of acoustic emissions from partial discharges andother sources in oil immersed power transformers and reactors. Both electrical sources (partial discharge)and mechanical sources (such as loose clamping, bolts, or insulation parts) generate these emissions. Thereare descriptions of acoustic instrumentation, test procedures, and interpretation of results. When this guideis used with oil-immersed reactors, it must be understood that interpretation of signals may be differentbecause of the construction of the reactor.Accuracy of location depends on the type of fault, configuration of tank, type of instrumentation, andexperience.
Purpose
This guide is intended to provide information that may be helpful in planning, installing, and operatingacoustic monitoring equipment and in meaningful interpretation of resulting data. Users are intended to bepersons knowledgeable in this field such as utility engineers, consultants, academics, and manufacturers.
Abstract
Revision Standard - Active.This guide is applicable to the detection and location of acoustic emissions from partial discharges and other sources in oil immersed power transformers and reactors. It is intended to provide a means of associating the relative magnitude and position of partial discharges and other sources with the acoustic signals obtained by strategically located transducers.
