Ngophuhliso olukhawulezayo lweegridi zamandla ezidolophini nasezilalini, uthungelwano lokuhambisa lujike lwalawulwa ziintambo.Olu tshintsho lukhokelela ekunyukeni okubonakalayoumhlaba capacitor okwangoku, okubangela ukuncitshiswa kweziphoso ezibuyiselwayo xa impazamo yomhlaba wesigaba esisodwa yenzeka kwinkqubo.Ukujongana nalo mngeni, ukuphunyezwa kwe-resistive grounding kuye kwaba yinto ebalulekileyo ukulungelelanisa iimfuno eziguqukayo zegridi yamandla ngelixa kuncitshiswa amanqanaba e-insulation yokuhanjiswa kwamandla kunye nezixhobo zokuguqula.
I-Resistive grounding ineenzuzo ezininzi, ezibandakanya ukunciphisa utyalo-mali kuyo yonke igridi yamandla, ukukwazi ukunqumla iziphene, ukucinezela i-resonant overvoltage, kunye nokwandisa ukhuseleko kunye nokuthembeka kwenkqubo yamandla.Enye yezona zinto zibalulekileyo zokuphumeza ukuxhathisa ukuxhathisa yikhabhinethi yokumelana nomgangatho, edlala indima ebalulekileyo ekuqinisekiseni ukusebenza kakuhle kwenkqubo yokumisa.
Iikhabhinethi zokumelana nomhlaba zenzelwe ukubonelela ngendlela elawulwayo yempazamo yangoku ukuhamba emhlabeni, ngokufanelekileyo ukukhawulela ukunyuka kombane ngexesha lempazamo yomhlaba.Ngokubandakanya ezi khabhinethi kwisiseko segridi, umngcipheko weengozi zombane kunye nomonakalo wezixhobo unokuncitshiswa kakhulu.Ukongezelela, ukusetyenziswa kweekhabhinethi zokumelana nomhlaba kunegalelo ekuzinzeni ngokubanzi kunye nokusebenza kwenkqubo yamandla, ekugqibeleni kuphuculwe ukusebenza kwayo.
Kwimeko yophuhliso oluqhubekayo loyilo lwegridi yamandla, ukuhlanganiswa kweekhabhinethi zokumelana nomhlaba kubalulekile ukuqinisekisa ukhuseleko kunye nokuthembeka kwenethiwekhi yokusabalalisa.Njengoko imfuno yokusebenza kakuhle, ukuhanjiswa kwamandla okuzinzileyo kuqhubeka nokukhula, indima yeekhabhinethi zokuchasana nomhlaba ekunciphiseni ubungozi obunokubakho kunye nokuphucula ukusebenza kwenkqubo kubaluleke kakhulu.
Isishwankathelo, ukusetyenziswa kweekhabhinethi zokumelana nomhlaba kunceda ukuxazulula imingeni ebangelwa ukuguquka kwezakhiwo zegridi.Ngokwamkela i-resistive grounding kunye nokusebenzisa iikhabhinethi zokumelana nomgangatho ophezulu, abaqhubi begridi banokuphucula ngokufanelekileyo ukhuseleko, ukuthembeka kunye nokusebenza kakuhle kwenethiwekhi yokusabalalisa, ekugqibeleni negalelo ekuphuhlisweni okuzinzileyo kweziseko zombane.
