Hauv kev siv hluav taws xob txhua hnub thiab kev faib hluav taws xob hauv kev lag luam, ob qho tib si circuit breakers thiab cov switches ib txwm siv. Lawv tuaj yeem pom hauv cov thawv faib khoom hauv tsev, cov tswj teeb pom kev zoo ntawm phab ntsa, thiab cov khoom siv faib hluav taws xob hauv Hoobkas, tab sis ntau tus neeg yooj yim ua rau lawv tsis meej pem. Qhov tseeb, qhov chaw tseem ceeb thiab cov haujlwm ntawm ob qho no txawv heev. Tsis tas yuav piav qhia nyuaj - koj tuaj yeem qhia qhov sib txawv tseem ceeb hauv ib feeb thiab yooj yim nkag siab txog lawv cov kev siv.
Lub luag haujlwm tseem ceeb ntawm ib qhoqhov hloov pauv ib txwm muajTsuas yog ib qho xwb: tsuas yog tswj qhov qhib-kaw ntawm lub voj voog. Piv txwv li, cov qhov hloov teeb hauv tsev, cov qhov hloov ntawm phab ntsa, lossis cov qhov hloov ntawm cov hlua fais fab txhua tus yog cov khoom no. Nws tsuas yog tuaj yeem tig lub voj voog rau lossis tawm los ntawm kev ua haujlwm tes thiab tsis muaj lub tshuab tiv thaiv tsis siv neeg. Txawm tias muaj xwm txheej txaus ntshai xws li kev thauj khoom ntau dhau (piv txwv li, ntsaws ntau lub cuab yeej hluav taws xob muaj zog rau hauv ib lub qhov) lossis luv luv tshwm sim hauv lub voj voog, lub qhov hloov pauv ib txwm tsis tuaj yeem hnov nws, tsis txhob hais txog kev txiav lub voj voog. Thaum kawg, nws yuav ua rau puas tsuaj rau cov khoom siv hluav taws xob thiab txawm tias ua rau muaj kev phom sij xws li hluav taws xob.
Thaum iblub tshuab hluav taws xobmuaj lub luag haujlwm yooj yim ntawm "tswj lub on-off ntawm lub voj voog", nws qhov zoo tshaj plaws yog tias nws muaj lubua-nyob rau hauv tsis siv neeg tiv thaiv kev ua haujlwm, uas kuj yog qhov sib txawv tseem ceeb ntawm nws thiab lub qhov hloov pauv ib txwm muaj. Thaum muaj xwm txheej tsis zoo xws li overload, luv luv, lossis xau hluav taws xob tshwm sim hauv lub voj voog, lub tshuab hluav taws xob yuav hnov qhov hloov pauv tam sim no hauv lub voj voog, txiav tawm lub voj voog, thaiv qhov txaus ntshai raws sijhawm, tiv thaiv cov khoom siv hluav taws xob kom tsis txhob kub hnyiab thiab cov kab los ntawm kev laus thiab ntes hluav taws, thiab ua kom muaj kev nyab xeeb hluav taws xob. Ntxiv mus, tom qab tripping, koj tuaj yeem kaw lub qhov hloov pauv manually kom rov siv dua tom qab teeb meem, uas yooj yim rau kev ua haujlwm.
Hais yooj yim xwb, lub qhov hloov hluav taws xob ib txwm tsuas yog lub luag haujlwm rau "kev qhib thiab kaw", thaum lub tshuab hluav taws xob tawg yog "lub qhov hloov + tus neeg saib xyuas kev nyab xeeb". Hauv kev siv hluav taws xob txhua hnub, ob qho tib si ua lawv txoj haujlwm los ua ke tiv thaiv kev nyab xeeb ntawm lub voj voog.
