Abstract

This paper presents a detailed review of the investigation and subsequent repairs undertaken by Hydro One in response to a sudden pressure trip of a 500 MVA phase shifting transformer. The paper underscores the importance of a thorough and comprehensive investigation. It also illustrates the complexities of troubleshooting a large phase shifting transformer and the importance of delineating between information pertinent to the problem and other unrelated abnormal conditions. The paper briefly touches on the importance of maintaining on-line diagnostic tools, and it describes the intrusive and atypical repairs undertaken to return the asset back to service.
