Yog vim li cas rau lub transformer backup tiv thaiv kev txiav txim yog:
(1) luv luv Circuit Court ntawm lub siab voltage sab ntawm lubtransformer.
(2) transformer low voltage bus luv luv Circuit Court.
(3) Kev tiv thaiv kev sib txawv tsis ua haujlwm vim qhov ua tsis tiav hauv qhov kev tiv thaiv sib txawv.
(4) Backup tiv thaiv misoperation.
(5) Cov kab hluav taws xob tsawg yog qhov ua txhaum, thiab kev tiv thaiv kab tawm tsis kam txav mus, ua rau lub tshuab hloov pauv mus dhau qhov kev thauj khoom.
Cov txheej txheem tswj hwm yog:
(1) Yog tias qhov kev tiv thaiv overcurrent, pom qhov poob qis, cuam tshuam, arc, suab thiab lwm yam tshwm sim, yuav tsum raug tshuaj xyuas sab nraum lub tshuab hloov pauv; Yog tias qhov txhaum tuaj yeem raug tshem tawm hauv lub sijhawm, nws tuaj yeem sim ua ib zaug, txwv tsis pub ntsuas kev nyab xeeb yuav tsum tau coj los npaj rau kev kho kom nrawm; Yog tias tsis pom muaj teeb meem, koj tuaj yeem sim xa ib qho; Rau cov transformers tsis muaj kev tiv thaiv sib txawv, ntxiv rau kev tshuaj xyuas sab nraud, kev ntsuas kev ntsuas hluav taws xob yuav tsum tau ua.
(2) Yog tias qhov hluav taws xob qis qis tsis ua haujlwm thiab kev tiv thaiv kab tsis kam txav mus los, koj tuaj yeem rub tawm cov kab hloov pauv tsis raug thiab tom qab ntawd siv lub tshuab hloov pauv.
(3) Yog tias qhov kev tiv thaiv kev sib txawv tsis ua tiav vim yog qhov ua txhaum ntawm qhov kev tiv thaiv sib txawv, nws yuav tsum tau ua tiav raws li qhov kev tiv thaiv sib txawv.
(4) Yog hais tias nws yog ib qho txhaum cai thib ob, nws yog kev ua haujlwm tsis raug lossis kev sib cuag tsis raug, thiab cov neeg ua haujlwm ntawm lub luag haujlwm tuaj yeem kuaj lub zog xa mus tam sim.
