Electrical Substation imagwira ntchito yofunika kwambiri pakugawa magetsi, kuwonetsetsa kuti nyumba, mabizinesi, ndi mafakitale zipezeka zodalirika. Ndi mawonekedwe ake olimba komanso zida zapamwamba, imakhala ngati malo ofunikira kwambiri potumiza ndikusintha mphamvu zamagetsi.

Mapangidwe a substation amakhala ndi zigawo zosiyanasiyana, kuphatikiza ma transfoma, ma circuit breaker, ndi switchgear, zokonzedwa mwadongosolo. Ma transformer ndi omwe ali ndi udindo wokweza kapena kutsitsa ma voltage kuti atumize ndikugawa bwino. Ma circuit breakers amateteza dongosolo kuti lisachuluke komanso mabwalo amfupi, pomwe switchgear imalola kudzipatula ndikuwongolera magawo osiyanasiyana a netiweki.

Malo ang'onoang'ono nthawi zambiri amakhala ndi nsanja, zomwe zimapereka chithandizo kumayendedwe apamtunda omwe amalumikiza ndi malo ena kapena malo opangira magetsi. Zinsanjazi zapangidwa kuti zizitha kupirira nyengo yovuta, zomwe zimapangitsa kuti magetsi azikhala olimba.

Poyendetsa bwino kayendedwe ka mphamvu ndi kutembenuka kwa magetsi, malo opangira magetsi amaonetsetsa kuti magetsi azikhala odalirika komanso osasokonezeka. Zimagwira ntchito yofunika kwambiri pakusunga bata ndi mtundu wamagetsi, potsirizira pake zimapindulitsa ogwiritsa ntchito mapeto.
