Research on Distribution Transformer Condition Assessment Method Based on Core State Variable Set

Abstract:

According to the problems that there are less distribution transformer state variables and the condition assessment of distribution transformer carry out difficultly, a method of distribution transformer condition assessment based on core state variables is presented. The initial results of distribution transformer condition assessment are obtained by using core state variables. Then through calculating the sensitivity of the non-core state variables to the evaluation results, the initial assessment results are modified to ensure more accurate results.
