Impact Of Transient Inrush On MOV Starting

Abstract

This paper is the result of a recent NRC concern with the impact of transient inrush current on motor operated valve (MOV) starting. It provides the background for this issue, discusses the accuracy of measured current traces, presents the theory behind transient inrush, analyzes a set of VOTES test data, and discusses its impact on motor starting to determine whether the concern had a valid, technical basis.
