Kugira ngo ikibazo gikemuke ku mbaraga nke mu itanura rya arc ryarengewe, igihugu cyanjye gikunze gukoresha indishyi zidasanzwe, ubusanzwe zikoreshwa kuruhande rwa - voltage. Nyamara, indishyi ndende - voltage impande zananiwe gukemura ibibazo bitatu -. Byongeye kandi, kubera ko reaction ya inductive ya rezo ngufi - ihwanye na 70% ya sisitemu yose uko yakabaye, indishyi ndende - ntizigabanya neza - rezo y'urusobe cyangwa kunoza ibintu bigufi -; ntanubwo igera ku ntego yo kongera umusaruro wa transformateur - inyungu zayo zigarukira gusa kumashanyarazi.
Kubera iyo mpamvu, ibigo bimwe na bimwe byashyizeho uburyo bubiri - bwo kwishyura indishyi - zikoresha indishyi z’amashanyarazi ku buryo bukabije - ndetse n’urwego ruto - urwego rw’amashanyarazi - kugira ngo itanura rishya rikemuke. Indishyi mugihe gito - iherezo ryurusobe rutezimbere cyane imbaraga zingufu kandi zigabanya gukoresha ingufu. Gushyira mubikorwa - imbuga zishyurwa kugirango zikemure ingufu zikoreshwa cyane hamwe nubusumbane bwicyiciro kumashanyarazi ahinduka - umuyagankuba - umuyoboro - mugihe icyarimwe uzamura ingufu z'amashanyarazi - ni igisubizo cyizewe kandi gikuze hamwe nigiciro cyiza -. Ugereranije n’indishyi nyinshi - indishyi, kuri - ikibanza cy’indishyi zidafite ingufu ku ruhande rwa voltage - zitanga inyungu zidasanzwe mu kuzamura ingufu z’amashanyarazi, kugabanya imikoranire, kongera umusaruro, no kugabanya gukoresha ingufu. Nyamara, uburyo bukubiyemo ibiciro byinshi hamwe nibikoresho bigenewe ibidukikije bikora nabi, bigabanya cyane ubuzima bwa serivisi. Byongeye kandi, hasi - voltage ngufi - indishyi zurusobe zirashobora kongera urwego ruhuza, bisaba ingamba zo guhagarika icya 3 - kugeza 7 - gutondekanya; ibi bitera ishoramari ryambere, byongerera igihe cyo kwishyura, kandi bikavamo amafaranga menshi yo kubungabunga no gukomeza ubukungu muri rusange. Kubwibyo, ubu buryo bukwiranye gusa nitanura ryubatswe.
