IEEE PC57.127 DRAFT 2017 Edition, October 1, 2017 Draft Guide for Detection, Location and Interpretation of Sources of Acoustic Emissions from Electrical Discharges in Power Transformers and Power Reactors
More info
Description / Abstract:
This guide is applicable to the detection and location of sources of acoustic emissions from partial discharges 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.
Safety warning
The safetywarnings in this subclause apply only to work done on transformers installed in the field, not to factory testing. Refer to factory test codes for safety warnings for these situations. Partial discharge (PD) location should only be attempted by those technicians and engineers trained in working on high-voltage transformers and knowledgeable of the risks associated with this work.
