摘要
通过对两起保护动作情况的分析 。
Based on the analysis of two transformer failures, it was found that the 'trip' circuit board of the relay system contained a design error. The 'trip' circuit board is powered by Direct Current from two sets of storage batteries. This paper discusses the cause of the failure and offers corrective action.
