此外回路損耗也使諧振過電壓受到阻尼和限制。當回路電阻大于一定的數(shù)值時，就不會出現(xiàn)強烈的鐵磁諧振過電壓。3）串聯(lián)諧振電路來說，產(chǎn)生鐵磁諧振過電壓的的必要條件是ω0=1/L0C<；因此鐵磁諧振可在很大的范圍內(nèi)發(fā)生。4）維持諧振振蕩和抵償回路電阻損耗的能量均由工頻電源供給。為使工頻能量轉(zhuǎn)化為其它諧振頻率的能量，其轉(zhuǎn)化過程必須是周期性且有節(jié)律的，即…1/2(1，3…）倍頻率的諧振。5）鐵磁諧振對PT的損壞。電磁諧振（分頻）一般應具備如下三個條件。①鐵磁式電壓互感器（PT）的非線性效應是產(chǎn)生鐵磁諧振的主要原因。②PT感抗為容抗的100倍以內(nèi)，即參數(shù)匹配在諧振范圍。③要有激發(fā)條件，如PT突然合閘、單相接地突然消失、外界對系統(tǒng)的干擾或系統(tǒng)操作產(chǎn)生的過電壓等。
