Liwiro lozungulira la ma hydraulic turbines ndi lotsika, makamaka pama hydraulic turbines. Kuti apange 50Hz alternating current, hydraulic turbine jenereta imatenga mapeyala angapo amitengo yamaginito. Kwa jenereta ya hydraulic turbine yokhala ndi zozungulira 120 pamphindi, mapeyala 25 a maginito amafunikira. Popeza ndizovuta kuwona kapangidwe kake ndi mitengo ya maginito yambiri, pepala ili likuwonetsa chitsanzo cha jenereta ya hydro-turbine yokhala ndi mapeyala 12 a maginito.
Rotor ya hydro-generator imatenga mawonekedwe owoneka bwino. Chithunzi 1 chikuwonetsa goli ndi mtengo wamagetsi wa jenereta. Mtengo wa maginito umayikidwa pa goli la maginito. Goli la maginito ndi njira ya mzere wa magnetic field wa magnetic pole. Mzati uliwonse umavulazidwa ndi koyilo yosangalatsa, ndipo mphamvu yachisangalalo imaperekedwa ndi jenereta yosangalatsa yomwe imayikidwa kumapeto kwa tsinde lalikulu, kapena kuperekedwa ndi kunja kwa thyristor excitation system (yoperekedwa ndi mphete ya wokhometsa kwa koyilo yosangalatsa).
Goli limayikidwa pazitsulo za rotor, shaft yaikulu ya jenereta imayikidwa pakatikati pa rotor bracket, ndipo jenereta yokondweretsa kapena mphete yosonkhanitsa imayikidwa kumapeto kwa shaft yaikulu.
Pakatikati pa stator chitsulo cha jenereta amapangidwa ndi mapepala achitsulo a silicon okhala ndi maginito abwino. Pali mipata yambiri yomwe imagawidwa mozungulira mkati mwachitsulo chachitsulo, chomwe chimagwiritsidwa ntchito kuyika ma coils a stator.
Ma coils a stator amaphatikizidwa mu mipata ya stator kuti apange mawindo a magawo atatu, mapiritsi a gawo lililonse amapangidwa ndi ma coils angapo ndipo amakonzedwa motsatira malamulo ena.
Jenereta ya hydro-jenereta imayikidwa pa pier yamakina yopangidwa ndi konkriti, ndipo maziko a makina amayikidwa pa pier ya makina. Pansi pamakina ndiye maziko oyika chitsulo cha stator ndi chipolopolo cha hydro-generator. Kuchepetsa kutentha kwa mpweya wozizira wa jenereta; chimango chapansi chimayikidwanso pa pier, ndipo chimango chapansi chimakhala ndi chowongolera kuti chiyike chozungulira cha jenereta. The thrust bear itha kupirira kulemera kwa rotor, vibration, impact ndi mphamvu zina.
Ikani pachimake chitsulo cha stator ndi stator koyilo pa chimango, rotor imayikidwa pakati pa stator, ndipo pali kusiyana kochepa ndi stator. Rotor imathandizidwa ndi kukankhira kwa chimango chapansi ndipo imatha kuzungulira momasuka. Ikani chimango chapamwamba, ndipo pakati pa chimango chapamwamba chimayikidwa ndi Chowongolera chimalepheretsa shaft yayikulu ya jenereta kuti isagwedezeke ndikuyisunga mokhazikika pakatikati. Ikani nsanja yapamwamba pansi, ikani chipangizo cha burashi kapena galimoto yosangalatsa, ndipo chitsanzo cha hydro-generator chimayikidwa.
Kuzungulira kumodzi kwa rotor ya mtundu wa hydro-jenereta kumapangitsa mikombero 12 ya mphamvu yamagetsi yamagawo atatu a AC. Pamene rotor ikuzungulira pa 250 kutembenuka pa mphindi imodzi, mafupipafupi a alternating panopa ndi 50 Hz.
