Predicting recloser failure rates from field condition assessment

Abstract

This research develops a technique to predict the failure rate of a power distribution system recloser. The prediction is based on suggested criterion given and defined within this paper. Because inspection practices differ among utilities, the technique will apply to whatever data is available, and make the best prediction from that data. Examples of using the technique are provided. Predicted failure rates can then be used in system simulations to predict system reliability indices, and the effect routine maintenance has on them.
