主变差动极性测试软件开发

摘要

Transformer and differential protection devices need test polarity with the load , This paper is to study a piece of differen-tial polar test software based on Matlab GUI. It can reduce significantly the operational time of transformer differential protection de-vices.%变压器及差动保护装置投入运行之前需要进行带负荷测试极性工作。基于Matlab GUI平台开发出来的差动极性测试软件，可以大大减少变压器及差动保护装置投入运行时间。
