Kurinda Surge ni tekinoroji igamije kurinda ibikoresho by'amashanyarazi amashanyarazi, cyangwa ingufu z'amashanyarazi. Inkuba ikubise, umuriro w'amashanyarazi, cyangwa ibibazo by'amashanyarazi birashobora gutera umuriro mwinshi. Uku kwiyongera kurashobora kwangiza cyangwa gusenya ibikoresho byamashanyarazi nka mudasobwa, televiziyo, nibindi bikoresho bya elegitoroniki. Kurinda kubaga byashizweho kugirango bigenzure voltage kandi birinde ibikoresho bihujwe na voltage iyo ari yo yose. Kurinda kubaga mubisanzwe bifite icyuma kizunguruka kigabanya ingufu mugihe habaye umuvuduko wa voltage kugirango wirinde kwangirika kw ibikoresho byamashanyarazi bihujwe. Kurinda kubaga akenshi bikoreshwa hamwe ningufu zamashanyarazi, kandi bitanga urwego rwingenzi rwo kurinda ibicuruzwa bya elegitoroniki yawe yoroheje.
