Ibura ry'amashanyarazi cyangwa amashanyarazi ku isi ririmo kwiyongera cyane. Ibigo byinshi n'abantu ku giti cyabo bahitamo kuguraamamashini akoresha mazutuku ikoreshwa ry'amashanyarazi kugira ngo bigabanye imbogamizi ku musaruro n'ubuzima bw'amashanyarazi biterwa n'ibura ry'amashanyarazi. Nk'igice cy'ingenzi cy'imashini zitanga amashanyarazi, alternators zidafite uburoso za AC zigira uruhare runini mu gihe cyo guhitamo gensets za mazutu. Hasi aha hari ibimenyetso by'ingenzi by'amashanyarazi bya alternators zidafite uburoso za AC:
1. Sisitemu yo gukurura. Sisitemu yo gukurura ya alternator igezweho ifite ubushobozi bwo kugenzura amashanyarazi (AVR mu magambo ahinnye), kandi stator yo kwakira itanga ingufu kuri stator yo gukurura amashanyarazi binyuze muri AVR. Ingufu zo gusohora za rotor yo gukurura amashanyarazi zoherezwa kuri rotor ya moteri nkuru binyuze muri rectifier yuzuye y’ibice bitatu. Igipimo kinini cyo guhindura amashanyarazi ya AVR zose ni ≤1%. AVR nziza cyane zifite imirimo myinshi nko gukora icyarimwe, kurinda amashanyarazi make, no kugenzura amashanyarazi yo hanze.
2. Gushyiramo ubushyuhe n'ubuvange. Uburyo bwo gukingira ibyuma by'ubushyuhe by'ubushyuhe muri rusange ni "H". Ibice byabyo byose bikozwe mu bikoresho byakozwe mu buryo bwihariye kandi bishyirwamo uburyo bwihariye, kugira ngo bitange garanti yo gukora mu bidukikije.
3. Gufunga no gukoresha amashanyarazi. Stator ya alternator nziza izashyirwamo ibyuma bikonje bifite ubushobozi bwo kwinjira neza mu kirere, ibyuma bifite imiterere ibiri, imiterere ikomeye kandi bifite ubushobozi bwo gukingira.
4. Interference kuri telefoni. THF (nk'uko byasobanuwe na BS EN 600 34-1) iri munsi ya 2%. TIF (nk'uko byasobanuwe na NEMA MG1-22) iri munsi ya 50
5. Kwivanga kwa radiyo. Ibikoresho bitagira uburoso na AVR byiza bitanga amahirwe make yo kwivanga kwa radiyo. Iyo bibaye ngombwa, hashobora gushyirwaho ikindi gikoresho cyo gukumira RFI.
