Power Fuse ni uburyo bwemewe muri rusange bwo kurinda transformateur z'amashanyarazi mu dusanduku duto dukwirakwiza umuriro. Intego nyamukuru ya Power fuse ni uguhagarika burundu ikibazo. Fuse ni ubundi buryo buhendutse bwo kurinda circuit switcher cyangwa circuit breaker.
Uburinzi bwa Fuse Ubusanzwe bugarukira kuri voltage ya 34.5 kv kuri kv imwe, ariko bwakoreshejwe mu kurinda transfoma za 138 kv. Kugira ngo habeho uburinzi ntarengwa, hagomba gukoreshwa igipimo gito gishoboka cya fuse. Akamaro ka fuse ifunze ni uko fuse irinda amakosa abiri. Ku transfoma zisanzwe zihuza impande eshatu, igipimo cya fuse cya 1.0 kizatanga uburinzi ku makosa ajyanye n'igihe, kugeza kuri 230% by'igipimo cya kabiri cy'umutwaro wose. Igipimo cya fuse gisobanurwa nk'igipimo cya fuse ku gipimo cy'umutwaro wose wa transfoma.
