3. Uvavanyo lwePower Factor:

Uvavanyo lwezinto ezibangela umbane lwenziwa ukuze kuvavanywe iimpawu ze-dielectric zenkqubo yokukhusela umbane. Olu vavanyo lulinganisa ukulahleka kwamandla kwi-insulation phantsi kwe-AC voltage. Ukufundwa kwezinto ezibangela umbane ophezulu kubonisa inqanaba eliphezulu lokuwohloka kwe-insulation, okunokubangela ukuqhekeka.

4. Uhlalutyo lwempendulo ye-Sweep Frequency (SFRA):

I-SFRA sisixhobo sokuxilonga esisetyenziselwa ukuvavanya ukuthembeka koomatshini bee-transformer windings. Olu vavanyo lubandakanya ukusebenzisa isignali ye-AC kuluhlu lwee-frequency kwi-transformer kunye nokulinganisa impendulo. Naziphi na iingxaki kwimpendulo ye-frequency zingabonisa ukuguquka koomatshini okanye ukufuduka kwee-windings, okunokukhokelela kwimpazamo.

5. Uhlalutyo lweGesi enyibilikisiweyo (i-DGA):

Uhlalutyo lwegesi enyibilikisiweyo yindlela esetyenziselwa ukuvavanya imeko yokufakwa kwe-insulation kunye nombindi we-transformer. Ubukho beegesi ezithile kwioyile ye-transformer bunokubonisa ukuba kukho iimpazamo zobushushu okanye zombane. I-DGA inokunceda ekuchongeni imiba enokubakho efana nokushisa kakhulu, ukujiya, okanye ukukhutshwa okuncinci kwi-transformer.
