Ibizamini bya insulasi bikurikira birakorwa kugirango uhuze imbaraga ziteganijwe.
Keretse niba byasabwe ukundi nabakiriya, ibizamini bikurikira bikorwa muburyo bukurikira (IEC 60076-3):
Guhindura ibizamini bya impulse: kwemeza ubwishingizi bwimikorere ya transformateur hamwe nu guhinduranya ibice byubutaka hamwe nizindi mpinduramatwara, no kwemeza imbaraga zokwirinda mumuzinga no kunyura.
Ikigeragezo cyumurabyo: kwemeza imbaraga zo guhinduranya insimburangingo mugihe inkuba ikubise itumanaho
Gutandukanya inkomoko AC kwihanganira ikizamini cya voltage: kwemeza imbaraga zokwirinda kumurongo wa transformateur hamwe na terefone ihuza itabogamye hamwe nu murongo uhuza ibice byubutaka nibindi bizunguruka.
Ikizamini cya voltage ya AC (igihe gito ACSD nigihe kirekire ACLD): kwemeza imbaraga zo gukumira insimburangingo ihuza imiyoboro ihinduranya hamwe nu murongo uhuza ibice byubutaka hamwe nizindi zizunguruka, haba hagati yicyiciro no kunyura.
Ibipimo byo gusohora igice: kwemeza "gusohora igice munsi yumutungo wagenwe wurwego rwimiterere ya transformateur mugihe cyimikorere.
Kugirango twigane umurabyo impulse voltage ikoreshwa kuri transformateur. Isosiyete ikora amashanyarazi ya Huayi ikora sisitemu yo gupima impulse ya voltage itanga ingufu, ikaba ahanini ikwiranye na impulse yuzuye ihanganira ikizamini cya voltage ya 110kV no munsi yibikoresho bya voltage ndende, kandi irashobora no gukoreshwa mugupima impulse kubindi bicuruzwa. Ikoresha tekinoroji ya PLC kandi ikoresha fibre optique ya - yohereza amabwiriza yo kugenzura no kugenzura ibikoresho, bityo ikirinda kwivanga kwa electronique no kuzamura umutekano wa sisitemu yo kugenzura na mudasobwa. Igikorwa cyo kugenzura gifite intoki, cyuzuye, na progaramu yo kugenzura gahunda, kandi imikorere kuri buri rwego irigenga kugirango yizere kwizerwa rya sisitemu. Ifata uburyo bwa thyristor voltage yo kugenzura kandi ifite sisitemu yo gupima voltage yo gupima. Intera iri hagati yumupira wumupira no gutandukanya umupira urashobora guhindurwa intoki cyangwa byuzuye kandi byerekanwa kumwanya wa LCD.
