DC biasing can cause transformers noise increasing, vibration intensified, local overheating and even damaged.
直流偏磁会导致变压器噪音增大、振动加剧，可能引起变压器局部过热甚至损坏。
Researches indicate that negative peak value of the output voltage of the testing winding is linear with the positive DC magnetic biasing potential;
研究得出，当磁芯中存在正偏磁时，检测绕组输出端电压的负峰值与直流偏磁磁势是线性关系；
