A USER’S PERSPECTIVE:
“Since economics and time do not allow plant personnel to repair all suspect motors, on-line partial discharge analysis allows users to compare motors and gauge degradation to determine which motors pose the greatest risk of failure…”

PERIODIC ON-LINE PARTIAL DISCHARGE MONITORING OF MOTORS & TURBINE GENERATORS
The test enables predictive maintenance on motor and turbine generator stator windings, resulting in increased availability and extension of operating life. The technique was introduced over two decades ago and has since been applied to over 6000 motors and turbine generators to identify deteriorated stator windings. It is by far the most popular method in the world for measuring motor and generator partial discharge (PD). The method is non-destructive and based on sound scientific and empirical principles, and is recommended by manufacturers and industry standards such as the IEEE Std. 1434-2000.
