Method for control of vacuum-injection impregnation stator of a high-voltage electric motor by continuous measurement of the electrical capacity product

Abstract

A method for monitoring the vacuum-pressure impregnation stator of a high-voltage electric motor by continuously measuring the electric capacitance product is proposed. Control devices are recommended and the criteria for the evaluating quality of impregnation are given. Keywords stator, electric motor, vacuum pressure impregnation, polymerization, case insulation
