Ikhabhinethi yokumelana neTransformer engathathi hlangothi

Kwigridi yamandla ye-6-35KV AC yenkqubo yamandla yelizwe lam, kukho iindawo ezingathathi hlangothi, ezisekelwe kwiikhoyili zokucinezelwa kwe-arc, ukuxhathisa okuphezulu okusekelwe phantsi, kunye nokumelana okuncinci okusekelwe phantsi.Kwinkqubo yamandla (ingakumbi inkqubo yonikezelo lwamandla othungelwano lwasezidolophini kunye neentambo njengemigca yothumelo ephambili), i-ground capacitive current inkulu, enokwenza ukuba kwenzeke "intermittent" arc overvoltage yomhlaba ineemeko ezithile "ezibalulekileyo", ezikhokelela kwi-arcing. Ukusetyenziswa kwendlela yokusekela indawo engathathi hlangothi yokuvelisa i-grounding overvoltage yenza umjelo wokukhupha amandla (intlawulo) kwi-grid-to-ground capacitance, kwaye ifake i-resissive current kwi-fault point, yenza ukuba i-grounding fault current ithathele ingqalelo. indalo yokumelana-i-capacitance, ukunciphisa kunye Umehluko we-angle yesigaba se-voltage kunciphisa izinga lokutsha kwakhona emva kokuba okwangoku kwindawo yecala liwela i-zero kwaye liphule imeko "ebalulekileyo" ye-arc overvoltage, ukwenzela ukuba i-overvoltage iyancipha ngaphakathi kwe-2.6 amaxesha ombane wesigaba, kwaye kwangaxeshanye uqinisekisa ukhuseleko lomhlaba olunovakalelo oluphezulu Isixhobo simisela ngokuchanekileyo kwaye sinqumle iziphene eziziiprayimari nezesibini ze-feeder, ngaloo ndlela zikhusela ngokufanelekileyo ukusebenza kwesiqhelo kwenkqubo.
