Ufata arahuza umugozi nubutaka, mubisanzwe ugereranije nibikoresho bikingiwe. Ufata arashobora kurinda neza ibikoresho byitumanaho. Iyo voltage idasanzwe ibaye, uwufata azakora kandi agire uruhare rwo kurinda. Iyo insinga y'itumanaho cyangwa ibikoresho bikora munsi yumubyigano usanzwe wakazi, uwatawe muri yombi ntazakora, kandi bifatwa nkumuzunguruko ufunguye hasi. Iyo umuyagankuba mwinshi ubaye hamwe no gukumira ibikoresho bikingiwe bikabangamiwe, uwata muri yombi azahita akora kugirango ayobore umuyaga mwinshi w’umuvuduko ukabije w’ubutaka, bityo bigabanye amplitude ya voltage kandi birinde insinga z’insinga n’ibikoresho. Iyo overvoltage ibuze, uwata muri yombi ahita asubira uko yari imeze, kugirango umurongo w'itumanaho ushobore gukora bisanzwe.
Kubwibyo rero, umurimo wingenzi wuwata muri yombi ni ukugabanya umuvuduko wogutemba no kugabanya agaciro karenze urugero rwibikoresho bikingiwe binyuze mumikorere yikinyuranyo cyisanzuye cyangwa irwanya umurongo, bityo bikarinda umurongo witumanaho nibikoresho. Abafata inkuba ntibashobora gukoreshwa gusa kugirango birinde umuyaga mwinshi uturuka ku nkuba, ariko kandi no kurinda gukora amashanyarazi menshi.
Uruhare rwabafata ni ukurinda ibikoresho bitandukanye byamashanyarazi muri sisitemu y’amashanyarazi kutangirika n’umuriro ukabije w’umurabyo, gukora amashanyarazi arenze urugero, hamwe n’umuvuduko ukabije w’amashanyarazi. Ubwoko nyamukuru bwabafata ni icyuho cyo gukingira, abafata valve na zinc oxyde. Ikinyuranyo cyo gukingira gikoreshwa cyane cyane kugabanya ikirere kirenga ikirere, kandi muri rusange gikoreshwa mukurinda umurongo winjira wa sisitemu yo gukwirakwiza amashanyarazi, imirongo hamwe nubutaka. Ubwoko bwa arvester na zinc oxyde ifata mugukingira insimburangingo ninganda zamashanyarazi. Muri sisitemu ya 500KV no munsi yayo, zikoreshwa cyane mukugabanya ikirere kirenze ikirere. Kurinda ibikubiyemo.
