變壓器剛出產(chǎn)時，沒有經(jīng)過惡劣環(huán)境長時間的考驗，外施其額定電壓和頻率的電源作試驗，繞組匝間、層間和段間的電壓不足以達(dá)到電介質(zhì)缺陷處的擊穿電壓難以造成這些絕緣缺陷處的放電和擊穿，這種存在絕緣故障隱患的變壓器與絕緣性能良好的同類變壓器的空載電流和空載功耗沒有太大的差別，故而難以發(fā)現(xiàn)這些隱患； </p> <p> 而感應(yīng)耐壓試驗給變壓器施加2倍額定電壓以上的電壓，可在縱絕緣缺陷處建立更高更集中的場強(qiáng)，繞組匝間、層間和段間的電壓達(dá)到并超過電介質(zhì)缺陷處的擊穿電壓；感應(yīng)耐壓試驗給變壓器施加頻率在2倍的額定頻率以上，較高的頻率又可以大幅降低固體電介質(zhì)的擊穿電壓，使得絕緣缺陷更容易被擊穿；感應(yīng)耐壓試驗所規(guī)定的外施電壓的作用時間亦可保證絕緣缺陷的擊穿；故感應(yīng)耐壓試驗可以可靠地檢測出變壓器縱絕緣性能的好壞。
