Description / Abstract:
This guide discusses both on-line and off-line partial discharge
(PD) measurements on complete windings of any type, as well as
measurements on individual form-wound coils and bars. Measurements
selected from those that are outlined may be appropriate for
application during the manufacture, installation, operation, and
maintenance of windings of ac electric machinery.
Purpose
The purpose of this guide is to identify test methods that may
be useful in the measurement of PD activity involving the
electrical insulation systems of ac electric machinery for quality
control and to detect winding aging.
