Abstract :
This is a review of one manufacturer´s efforts toward testing NEMA low voltage motor insulation for compatibility with adjustable speed drives. PDIV (partial discharge inception voltage) measurements were selected as a tool to evaluate the future performance of the stator insulation system to resist deterioration by the drives. PDIV measurement is explained in terms of procedure and accuracy. Data is presented from tests made on motors from several prominent manufacturers.
