Isifinyezo

Isivikelo sombani esihlanganisiwe esinezigaba ezintathu siwuhlobo olusha lwesivikelo sombani esisetshenziswa kakhulu ukuvikela i-transformer, iswishi, i-bas bar, i-electrometer, i-capacitor ehambisanayo. Kuhlelo lukagesi lwe-35kV, singanciphisa futhi i-over-voltage yomoya, i-vacuum circuit breaker, i-phase to earth, i-phase to phase.
Isivikelo sombani esihlanganisiwe esinezigaba ezintathu siqukethe izivikelo zethu zombani ngohlobo lwezinkanyezi ezine, Ngakho-ke singavikela isigaba ngasinye emhlabeni kanye nesigaba kuya kwesinye kusukela ku-over-voltage, ngenxa yesakhiwo saso esihlakaniphile, umsebenzi waso ulingana nezivikelo zombani eziyisithupha, futhi sixazulula inkinga yokuthi izivikelo zombani azikwazi ukuvikela isigaba kuya kwesinye kahle. Isivikelo sombani esihlanganisiwe esinezigaba ezintathu singaba yigebe noma singabi nochungechunge.
