C57.117-1986 - IEEE Guide for Reporting Failure Data for Power Transformers and Shunt Reactors on Electric Utility Power Systems
Description: The guide addresses the reporting and statistical analysis of reliability of power transformers and shunt reactors used on electric utility power systems. The guidelines set forth cover the format for the collection and reporting of data. The guide illustrates the kinds of reports that may be useful to both users and manufacturers of transformers. The user is cautioned in the direct use of historical data collected for predicting reliability of future installations. These data are useful in pointing out areas of concern in design, application, installation, operation, and maintenance of transformers and shunt reactors that should be considered when predicting future reliability.
