1. Incamake

Valve yo kuvomera amazi ya MV na HV ifite ingufu nyinshini valve yihariye yagenewe by'umwihariko transformers zifite ingufu nyinshi (cyane cyane mu bihe nka transformers zo mu bwoko bwa box zo muri Amerika na substations zateguwe mbere). Inshingano yayo y'ingenzi ni ukurekura umuvuduko wa peteroli na gaze uturuka muri transformer bitewe n'ikibazo cyo gushyushya, ubushyuhe bukabije, cyangwa gusohora arc. Izirikana kandi uburyo bwo kuziba, kurwanya ingese, no koroshya imikorere. Igishushanyo cyayo gihuye n'amahame y'inganda z'amashanyarazi zo muri Amerika (nka IEEE C57 series, ANSI/IEEE 386). Ijyanye n'imiterere y'imashini transformers zo muri Amerika (nk'ibigega by'amavuta bito n'ibipimo bya flange interface). Ni igice cy'ingenzi mu kwemeza ko transformers zikora neza.

 2. Fkuryas

Kugabanya umuvuduko neza, birinda guturika k'umuvuduko ukabije

Uburinzi bufunze neza, nta gusohoka kw'amazi

Irwanya isuri n'imiterere y'amavuta iramba

Irahuye n'imashini zihindura ikirere zo mu bwoko bwa Amerika.

3.Porogaramus

Ikoreshwa cyane cyane ku byuma bihindura amashanyarazi bifite ingufu nyinshi byo mu bwoko bwa Amerika (nk'ibice by'amashanyarazi byo mu bwoko bwa Amerika, ibice by'amashanyarazi bihindura amashanyarazi, n'ibice by'amashanyarazi byateguwe mbere), cyane cyane bikoreshwa kuri:

· 1). Ibintu bikenewe cyane kugira ngo ibikoresho bigerweho mu mutekano mu mijyi, mu nganda, nibindi;

· 2). Ahantu hangiritse nko mu bushyuhe bwinshi, mu gusiga umunyu cyangwa mu gusiga imiti (hasabwa guhitamo imiyoboro irinda kwangirika);

· 3). Sitasiyo z'ikoranabuhanga zisaba igenzura kenshi cyangwa zidafite abapilote (birasabwa kugira imikorere yo gusubiza ibimenyetso).
