| 摘 要： | 本文介绍一种利用380V厂用电源进行发电机一次通流试验,以检查有关TA变比及相差的方法。通过改进TA相位及极性的检查方法,从而解决当TA变比较大导致二次电流较小时无法准确进行相位测试的问题。此试验方法简单、准确,满足测试要求,节约了发电机整套启动时的试验时间。

| Abstract: | A method about generator flow-through test using 380V auxiliary power to check TA ratio and phase difference is introduced in this article.The improvement of TA and polarity checking method is helpful to test the phase more accurately when the secondary current get smaller caused by the great TA ratio.The method is accurate and easy to operate.It could meet the testing requirements and save the testing time when the whole generator starts. |
