此外回路损耗也使谐振过电压受到阻尼和限制。当回路电阻大于一定的数值时，就不会出现强烈的铁磁谐振过电压。3）串联谐振电路来说，产生铁磁谐振过电压的的必要条件是ω0=1/L0C<；因此铁磁谐振可在很大的范围内发生。4）维持谐振振荡和抵偿回路电阻损耗的能量均由工频电源供给。为使工频能量转化为其它谐振频率的能量，其转化过程必须是周期性且有节律的，即…1/2(1，3…）倍频率的谐振。5）铁磁谐振对PT的损坏。电磁谐振（分频）一般应具备如下三个条件。①铁磁式电压互感器（PT）的非线性效应是产生铁磁谐振的主要原因。②PT感抗为容抗的100倍以内，即参数匹配在谐振范围。③要有激发条件，如PT突然合闸、单相接地突然消失、外界对系统的干扰或系统操作产生的过电压等。

脉宽可变触发技术，能提供足够到达晶闸管擎驻电流的锁定时间，避免窄脉冲触发不可靠。（包括电阻炉、加温器、烘箱、烘道、、红外辐射加温灯管等）等的温度自己/手动操控（升温、恒温、自己控温）和应用于调压、调光、交直流电机调速、电镀、蓄电池充电等设备，尤其适用于热惯性较小的电加温系统。（2）热惯性较大类：硅钼、钼丝、钨、白金冷热阻变化大，但电阻与温度关系呈线性，采用降压变压器、XCT1电流限制等，可设计低、中、高温区的电流限制。此外可采用SR53线性限幅，输出功率能自己跟随仪表的设定值线性增加。[3]调压调功一体化技术调压方式具有负载电流冲击小，适合变压器操控，但不可避免带来电源污染，降低功率因数。过零调功方式无法限制电流。
