Ingufu zo Gushyira Imbere mu Gikari za GN30-12

Imashini yo gutwikira MV yo mu nzu izunguruka ya GN30-12 (D) ni uburyo bushya bwo gutwikira icyuma cyo mu bwoko bwa icyuma gizunguruka, imiterere nyamukuru ishingiye ku matsinda abiri y’ubwishingizi n’aho ihurira ku ruhande rubiri rw’icyuma cy’ibyiciro bitatu, binyuze mu buryo bwo gutwikira icyuma, bigatuma icyuma kizimya umuriro.
Imashini ya GN30-12 (D) ni icyuma gishya cyongereweho ku butaka gishingiye ku gikoresho cya GN30-12, gishobora guhaza ibyifuzo by'uburyo butandukanye bw'amashanyarazi.
Igishushanyo mbonera cy'igicuruzwa gifite umwanya muto, gito gikoreshwa, ubushobozi bukomeye bwo kwirinda ubushyuhe, byoroshye gushyiraho no guhindura, imikorere yacyo ihuye n'ibisabwa na GB1985-89 bya "AC high voltage isolation switch and the grounding switch", bikoreshwa kuri voltage ya 10kV AC 50Hz no munsi ya sisitemu y'amashanyarazi yo mu nzu, kugira ngo gifungure kandi gifunge circuit iyo gishyizwemo voltage, nta mutwaro. Gishobora gukoreshwa hamwe n'akabati k'amashanyarazi gafite voltage nyinshi, kandi gishobora no gukoreshwa ukwacyo.
