据试验分频谐振的电流为正常电流的240倍以上，工频谐振电流为正常电流的40～60倍左右，高频谐振电流更小。在这些谐振中，分频谐振的破坏，如果PT的绝缘良好，工频和高频一般不会危及设备的，而6kV系统存在上述条件。消除办法从技术上考虑，为了避免铁磁谐振的发生，可以采取以下措施：选择励磁特性好的Tv或改用电容式TV；在同一个10kV配电系统中，应尽量减少TV的台数；在三相TV一次侧中性点串接单相TV或在TV二次开口三角处接入阻尼电阻；在母线上接入一定大小的电容器，使容抗与感抗的比值小于0.01，避免谐振,；系统中性点装设消弧线圈；采用自动调谐原理的接地补偿装置，通过过补、全补和欠补的运行方式，来较好地解决此类问题。
