The inductivereactance of a primary coil is much larger than the value of load resistance converted into the primary;
变压器原边线圈电感的感抗远远大于负载电阻对原边的折算值；
2
The variety of current can be automatic compensated caused by undulating of voltage & secondary loop inductivereactance.
对焊接电流进行反馈恒流控制，自动补偿网压波动、二次回路感抗变化对焊接电流的影响；
3
This situation occurs because noise cancellation depends on the fact that the inductivereactance of the windings must be much larger than the impedance of the cable.
