Note: The power supply shall be test at max AC voltage (270Vac) and min load or no load.
应该在最大交流输入电压270伏和轻载，空载下测试。
Based on the results of no load and load test, the paper studies the analysis and judgment methods of power transformer faults, and gives some field examples.
介绍根据空载试验及负载试验结果分析判断变压器故障的方法，并给出若干实例。
In the no-load test of transformer, because of the low power factor and non-sinusoid current waveform, the high precision measurement is difficult.
变压器的空载试验中，由于功率因数低，空载电流不是正弦信号，高精度测量其有功功率具有一定的难度。
