Transformateur ikoreshwa mu mavuta ni ubwoko bushya bwa transformateur ikora neza cyane. Amavuta akoreshwa nk'uburyo bw'ingenzi bwo gukingira amashanyarazi muri transformateur. Ibice by'ingenzi bigizwe n'inkingi y'icyuma, izunguruka, radiator, nibindi, kandi bikoreshwa cyane mu nganda z'amashanyarazi. Transformateur y'ubwoko bwumye ni transformateur ifite inkingi y'icyuma n'izunguruka bidashyirwa mu mavuta azunguruka. Igizwe ahanini n'inkingi y'icyuma n'izunguruka. Ifite ibyiza byo kudakoresha amashanyarazi menshi, ingano ntoya n'urusaku ruto.
Itandukaniro riri hagati ya transfoma zibitswe n'amavuta n'imashini zumye zirimo:
1. Uburyo butandukanye bwo gupakira
2. Imiterere itandukanye y'indorerwamo
3. Ubushobozi butandukanye n'imbaraga z'amashanyarazi
4. Uburyo butandukanye bwo gukingira no gutwika ubushyuhe
5. Ahantu hatandukanye hakurikizwa
6. Ubushobozi butandukanye bwo gutwara imizigo
