Managing existing transformers in the grid transition

Brian Sparling ; IEEE

Abstract

In the past eight or more decades, the electric power industry used a rating system based on conservative assumptions to determine the capacity available which lines and substations could use to safely carry the load. These are known as static lines ratings (SLR) systems, and substation capacity has had similar determinations made based on static or nameplate data of the equipment. It remains in use but is a very conservative method. Two newer methods evolved over time. One is the seasonally adjusted rating (SAR) system and the ambient adjusted rating (AAR), but they still rely on weather-related assumptions rather than real-time information.
