At A Glance

A unique opportunity exists to leverage the large volumes of existing measurements of voltage and current in a substation for monitoring asset condition. The key research questions are which assets in the substation would be ideal candidates for this solution and how to determine the condition of those assets from voltage and current measurements.

The project objective is to effectively utilize the existing data streams of voltage and current for diagnosis of equipment. The significant advantage is that the voltage and current signals are already being measured for other functions (protection, metering). If these same signals could also be utilized to provide insights into asset condition, it may present an opportunity to reduce the O&M costs of condition monitoring of a wide range of substation apparatus. If successful, the monitoring results could provide insights into the condition of a wide range of substation apparatus including instrument transformers, arresters, breakers, transformers and disconnect switches.
