Scope
Main technical content: This document specifies the multi-parameter monitoring method for DC biasing of power transformers and the evaluation method for the impact of DC biasing on transformers based on multi-parameter monitoring. This document is applicable to the multi-parameter monitoring of DC biasing of power transformers with a system voltage level of 110 kV and above, as well as the evaluation of the impact of DC biasing on transformers. Other voltage levels may refer to and implement this document accordingly.
