Abstract

A program is presented for prolonging the useful life of major equipment used in the auxiliary distribution systems of nuclear generating plants, with a focus on power quality and power conditioning. Both reactive power compensation and control of power quality have a significant impact on the life of electrical equipment. Improvements result from reduced operating temperatures, from systematic load reduction in the distribution system, and from reductions in phase imbalances and harmonics. This paper focuses on the impact of power conditioning on the life of transformers, cables, breakers, motors, and solenoids
