In the no-loadtest 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。

The test shows that the non-equality and unknown stress distribution of weld joint, which can be promoted by extra-load, is the key to make sure the steel pressure vessel for safety.
