电力变压器操作冲击试验的分析与改进

A Little Consideration of Switching Surge Test for Lorgo Power Transformer

本文分析了高压变压器进行操作冲击试验的现状,提出用直流励磁法代替传统的操作冲击励磁法,有助于提高试验结果的准确性。

This paper analyzes the condition of switching surge test for transformer and presents that it is helpful to improve the accuracy of the test result by exciting transformer with DC supply instead of the traditional switching impulse.
