Ukukhutshwa koxinzelelo lwe-transformer yamandla ngokwenene yivalve ecinezelwe ngentwasahlobo. I-valve inomsebenzi wokwandisa ngokukhawuleza amandla okuqala, kwaye isetyenziselwa ukukhulula ukunyuka kwengcinezelo ngokukhawuleza kwi-tank yeoli ye-transformer yamandla kunye nokukhusela itanki yeoli ye-oyile-i-oil-immersed power transformer. Kuphephe umonakalo kwitanki yamafutha. Xa uxinzelelo lwangaphakathi lwetanki yeoli lukhutshwa lungaphantsi koxinzelelo lwentwasahlobo, uxinzelelo lwentwasahlobo luya kuvala ngokuzenzekelayo i-valve ukuphepha ukugqithiswa kweoli ye-transformer. Xa i-pressure releaser isebenza, isignali ye-alarm iya kukhutshwa. Ibhokisi yesiphambuka yomqondiso kufuneka igcinwe yomile ukuze kuthintelwe izilumkiso zobuxoki xa amanzi engena kwaye efumile. Ngelo xesha, ingqalelo kufuneka ihlawulwe kwixesha lentwasahlobo, kwaye kufuneka ihlolwe rhoqo ukuba kuyimfuneko.

Izikhuseli zoxinzelelo zivame ukufakwa phezu kweetanki ze-oyile zokuguqula amandla okunciphisa ukunciphisa uxinzelelo lwe-static ngexesha lokusebenza okuqhelekileyo. Ukuze kuthintelwe i-oyile eshushu ukuba itshizwe kwisixhobo kunye nabasebenzi xa isebenza, umbhobho we-oyile yesikhokelo ungasetyenziselwa ukunqanda i-oyile etshiziweyo kumbhobho kwaye ungene kwi-oyile esisiseko.

Kwiinguqu zamandla ezinkulu ezifakwe kwioli enexabiso elingaphezulu kweoli, ii-releases ezimbini zoxinzelelo kufuneka zifakwe.
