Mawilo a Pelton ndi turbine wamba wamagetsi ang'onoang'ono a hydro-power, pomwe gwero lamadzi lomwe likupezeka lili ndi mutu wapamwamba kwambiri wa hydraulic pamayendedwe otsika, pomwe gudumu la Pelton ndi lothandiza kwambiri. Mawilo a Pelton amapangidwa mosiyanasiyana, kuchokera ku ma Hydro Systems ang'onoang'ono mpaka akuluakulu kuposa mayunitsi ang'onoang'ono a 10 MW omwe angafune.
Pogwira ntchito, pamene jeti yamadzi imalowa pazidebe zokhotakhota, mayendedwe amadzi amasinthidwa kuti atsatire mikombero ya chidebecho. Mphamvu yamadzi imatulutsa torque pa chidebe ndi gudumu, ndikuzungulira gudumu; mtsinje wamadzi wokha umapanga "u-turn" ndikutuluka kumbali zakunja za chidebecho, kutsika kwambiri. Pochita izi, mphamvu ya jeti yamadzi imasamutsidwa ku gudumu ndikuchoka ku turbine. Chifukwa chake, mphamvu ya "impulse" imagwira ntchito pa turbine. Kuti mukhale ndi mphamvu zambiri komanso zogwira ntchito bwino, magudumu ndi makina opangira magetsi amapangidwa kotero kuti kuthamanga kwa ndege yamadzi kumakhala kawiri kuthamanga kwa ndowa zozungulira. Gawo laling'ono kwambiri la mphamvu ya kinetic yoyambirira ya jet yamadzi idzakhalabe m'madzi, zomwe zimapangitsa kuti chidebecho chichotsedwe pamlingo womwewo womwe umadzazidwa, ndipo potero amalola kuti kulowetsedwa kwamphamvu kwambiri kupitirire mosadodometsedwa komanso popanda kuwononga mphamvu. Nthawi zambiri zidebe ziwiri zimayikidwa mbali ndi mbali pa gudumu, zomwe zimalola kugawa ndege yamadzi kukhala mitsinje iwiri yofanana. Izi zimalinganiza mphamvu zolemetsa mbali pa gudumu ndikuthandizira kuonetsetsa kusamutsa bwino, koyenera kwa jet yamadzi yamadzi kupita ku gudumu la turbine.
