Rotating electrical machines - Part 27-1: Off-line partial discharge measurements on the winding insulation

IEC 60034-27-1:2017 provides a common basis for:

- measuring techniques and instruments;

- the arrangement of test circuits;

- normalization and testing procedures;

- noise reduction;

- the documentation of test results;

- the interpretation of test results,

with respect to partial discharge off-line measurements on the winding insulation of rotating electrical machines.

This International Standard cancels and replaces IEC TS 60034-27 (2006). It constitutes a technical revision and reflects numerous improvements and corrections with respect to the previous publication.
