Abstract

During a routine inspection of a large pump motor at power plant, white powder was found on the surface of the stator end windings. Visual inspection and high voltage insulation diagnosis was performed to determine whether this motor is available. The purpose of this paper is to understand the insulation properties of white powder found on high voltage stator and to know prevention of insulation weakness.
