IEEE C57.127 2007 Edition, March 22, 2007 Guide for the Detection and Location of Acoustic Emissions from Partial Discharges in Oil-Immersed Power Transformers and Reactors
More info
Description / Abstract:
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. Both electrical sources
(partial discharge) and mechanical sources (such as loose clamping,
bolts, or insulation parts) generate these emissions. There are
descriptions of acoustic instrumentation, test procedures, and
interpretation of results. When this guide is used with
oil-immersed reactors, it must be understood that interpretation of
signals may be different because of the construction of the
reactor. Accuracy of location depends on the type of fault,
configuration of tank, type of instrumentation, and experience.
Purpose
This guide is intended to provide information that may be helpful in planning, installing, and operating acoustic monitoring equipment and in meaningful interpretation of resulting data. Users are intended to be persons knowledgeable in this field such as utility engineers, consultants, academics, and manufacturers.
