Chiziviso Chekuraira
Nzvimbo yekushanda kwechigadzirwa uye zvinodiwa zvakakosha:
1. Ipai madhirowa ekuodha zvigadzirwa, ayo anofanira kusanganisira madhayagiramu emagetsi uye anoratidza kugona kwetransformer, marongero emhando huru, maseketi ebazi rekugovera, uye kugona kwayo.
2. Kana zvichidikanwa kugadzirisa metering yemagetsi uye zvishandiso zvekugadzirisa otomatiki zvemagetsi zvinoitwa otomatiki, zvinodiwa zvekugadzirisa metering mita netransformer zvinofanirwa kupihwa, uye kugona kwe capacitor yemubhadharo kunofanirwa kuratidzwa.
3. Taura zvinodiwa pakugadzirisa pamusoro pechigadzirwa
