Pankhani ya uinjiniya wamagetsi ndi kugawa mphamvu, "substation structure" imatanthawuza mawonekedwe akuthupi omwe amathandizira magawo osiyanasiyana a siteshoni. Kapangidwe kameneka ndi kofunikira kuti pakhale ntchito yotetezeka komanso yogwira ntchito yamagetsi, makamaka pamagetsi othamanga kwambiri. Kuphatikizidwa kwazitsulo zamapangidwe, zitsulo zamagetsi ndi zipangizo zina zimagwira ntchito yofunika kwambiri pakupanga ndi ntchito ya substation.

Malo opangira magetsi ndi gawo lofunikira la gridi yamagetsi, omwe amagwira ntchito ngati malo omwe amasinthira magetsi kuchokera kumagetsi apamwamba kupita kumagetsi otsika kuti agawidwe kunyumba ndi mabizinesi. Magawo a substation amakhala ndi zinthu zosiyanasiyana, kuphatikiza ma transfoma, ma circuit breakers, ndi switchgear, zonse zomwe ndizofunikira pakuwongolera magetsi. Mawu oti "substation structure" amatanthauza momwe zinthu zilili komanso dongosolo lomwe lili ndi zigawozi, kuwonetsetsa kuti zimagwira ntchito moyenera komanso moyenera.

Chitsulo ndicho chinthu choyambirira chomwe chimagwiritsidwa ntchito pomanga nyumba zapansi panthaka chifukwa cha mphamvu zake, kulimba kwake, komanso kuthekera kopirira zinthu zachilengedwe. Chitsulo chachitsulo chimagwiritsidwa ntchito pomanga chimango cholimba chomwe chimatha kuthandizira zida zamagetsi zolemera komanso kupirira nyengo yovuta. Kugwiritsa ntchito chitsulo chamagetsi chopangidwira magetsi kumatha kuwonjezera mphamvu ya ma transfoma ndi zida zina mkati mwa substation.

Mapangidwe a substation nthawi zambiri amakhala ndi mitengo yachitsulo, yomwe imakhala yofunikira pothandizira mawaya apamwamba. Mitengoyi iyenera kupangidwa mosamala kuti zisapirire zolemetsa zazikulu komanso kuti zisapindane kapena kuthyoka chifukwa cha kupsinjika. Kuphatikizira mizati yachitsulo m'mapangidwe a substation kumatsimikizira kuti dongosolo logawa limakhala lokhazikika komanso lodalirika.

Mapangidwe ndi mapangidwe a substation amatsatiridwa ndi miyezo ndi malamulo otetezedwa. Kugwiritsa ntchito zitsulo zamtengo wapatali ndikofunikira kuti zitsimikizire kuti nyumbayo imatha kupirira zovuta zamagetsi, nyengo yoopsa, ndi zoopsa zina. Kapangidwe koyenera ka kagawo kakang'ono kamathandiza kupewa ngozi ndikuwonetsetsa chitetezo cha ogwira ntchito ndi madera ozungulira.

Kuonjezera apo, mapangidwe a mawonekedwe a substation ali ndi mphamvu yaikulu pakuchita bwino kwa kugawa mphamvu. Malo opangidwira bwino amatha kuchepetsa kutayika kwa mphamvu panthawi ya kusintha ndi kugawa, potsirizira pake kupeza mphamvu yodalirika yoperekera mphamvu. Kuyika kwadongosolo kwa zida zamagetsi mkati mwa kagawo kakang'ono kumathandizanso kukonza magwiridwe antchito ndikuchepetsa mtengo wokonza.
