Isikhiphi sokucindezela se-transformer yamandla empeleni siyivalvu ecindezelwe ngesiphethu. I-valve inomsebenzi wokukhulisa ngokushesha amandla okuqala, futhi isetshenziselwa ukukhulula ukukhuphuka kwengcindezi esheshayo ethangini lamafutha le-transformer yamandla futhi ivikele ithangi likawoyela le-transformer yamandla ecwiliswe ngamafutha. Gwema ukulimala ethangini likaphethiloli. Lapho ukucindezela kwangaphakathi kwethangi lamafutha kukhishwa ngaphansi kokucindezela kwentwasahlobo, ukucindezela kwentwasahlobo kuzovala ngokuzenzakalelayo i-valve ukugwema ukuchichima ngokweqile kwamafutha e-transformer. Uma isikhiphi sokucindezela sisebenza, isignali ye-alamu izokhishwa. Ibhokisi lokuhlanganisa isignali kufanele ligcinwe lomile ukuze kugwenywe izixwayiso zamanga lapho amanzi engena futhi eswakama. Ngesikhathi esifanayo, ukunakwa kufanele kukhokhwe ekufikeni kwesikhathi kwentwasahlobo, futhi kufanele kuhlolwe njalo uma kunesidingo.

Izikhiqizo zokucindezela zivame ukufakwa phezu kwamathangi e-transformer amandla acwiliswe ngamafutha ukuze kuncishiswe ingcindezi emile ngesikhathi sokusebenza okuvamile. Ukuze uvimbele ukuthi uwoyela oshisayo ungafuthwa ezintweni zokusebenza kanye nabasebenzi uma usebenza, ipayipi eliqondisa uwoyela lingasetshenziswa ukukhawulela uwoyela ofuthwe epayipini futhi ugeleze ungene echibini likawoyela eliyisisekelo.

Kuma-transformer amakhulu acwiliswe ngamafutha anenani elingaphezu kwenani elithile lamafutha, kufanele kufakwe izikhiqizo ezimbili zokucindezela.
