Kev kub siab yog ib qho kev pheej hmoo tsis txaus ntshai. Cov hluav taws xob hluav taws xob (hloov hloov) uas tsuas yog siv sib cais thib ob yog tshwm sim los ntawm cov hluav taws xob ncaj qha, nyob ze thiab nyob deb lossis tshem tawm haujlwm ntawm lub zog hluav taws xob.

Tus thawj coj nyob ze ntawm lub teeb hluav taws xob yog xob laim ntaus rau hauv lub tsev, hauv qhov chaw nyob ze lossis hauv cov kab nkag hauv tsev (piv txwv li hluav taws xob muaj hluav taws xob qis, xov tooj sib txuas xov tooj, thiab cov kab xov tooj). Qhov ntau thiab lub zog ntawm cov ntsiab lus ntawm cov tshwm sim tam sim no thiab cov hluav taws xob tsis zoo nrog rau cov xaim hluav taws xob (LEMP) cuam tshuam rau lub system kom muaj kev tiv thaiv.

Cov xob laim tam sim no los ntawm kev tawm tsam hluav taws xob ncaj qha mus rau hauv ib lub tsev ua rau muaj qhov nce ntawm ntau qhov 100,000 ntau qhov ntawm txhua qhov khoom siv earthed. Kev nce siab yog tshwm sim los ntawm qhov hluav taws xob poob ntawm qhov tshwm sim pob ntseg uas tshwm sim thiab qhov tshwm sim muaj peev xwm sawv ntawm lub tsev nrog txoj cai ib puag ncig. Qhov no yog qhov kev ntxhov siab tshaj plaws ntawm cov hluav taws xob hauv cov tsev.

Ntxiv rau qhov hluav taws xob poob ntawm qhov tso tawm pob ntseg tsis zoo, kev cia siab tshwm sim hauv kev teeb tsa hluav taws xob ntawm lub tsev thiab hauv cov kab ke sib txuas thiab cov khoom siv vim qhov cuam tshuam ntawm qhov hluav taws xob xob hluav taws xob. Lub zog ntawm cov kev ntxias thiab cov txiaj ntsig ntawm lub zog tam sim no qis dua li ntawm cov hluav taws xob ncaj qha tam sim no.

Cov chaw taws teeb hluav taws xob yog lub teeb hluav taws xob nyob deb ntawm qhov khoom yuav tsum tiv thaiv, hauv nruab nrab-voltage overhead kab network lossis hauv nws qhov sib ze raws li zoo li huab tawm mus rau huab.

Hloov kev ua haujlwm ntawm cov cuab yeej siv hluav taws xob ua rau mob siab ntxiv (SEMP - Hloov Mus Rau Electromagnetic Pulse) ntawm qee cov hluav taws xob hluav taws xob 1,000. Lawv tshwm sim, piv txwv li, thaum muaj teeb meem sib xyaws (piv txwv li transformers, reactors, qoj) hloov mus, arcs raug taws lossis fuses ncig. Yog tias lub hwj chim muab hluav taws xob thiab cov kab xov hluav taws xob raug muab sib txuas, lub tshuab hluav taws xob kuj yuav cuam tshuam nrog lossis rhuav tshem.

Kev hloov pauv hauv cov tsev nyob hauv ib thaj chaw, chaw haujlwm thiab cov thawj coj thiab cov chaw ua haujlwm hauv tsev lag luam muaj feem ntau tshwm sim nyob rau hauv, piv txwv li lub kaw lus fais fab, cov ntaub ntawv siv thev naus laus zis thiab cov xov tooj, tswj cov kab ke ntawm cov chaw tsim hluav taws xob los ntawm Fieldbus thiab tswj cov cua txias lossis teeb pom kev zoo Cov. Cov kab mob sib tiv thaiv no tsuas tuaj yeem tiv thaiv los ntawm kev siv lub tswv yim tiv thaiv. Hauv cov ntsiab lus no, kev sib koom tes ntawm kev siv kev tiv thaiv hluav taws xob (xob laim tam sim no thiab cov neeg txaij txav tawm) yog qhov tseem ceeb tshaj.

Kev ua haujlwm ntawm xob laim tam sim no cov neeg raug ntes tawm yog tso tawm lub zog siab tsis muaj kev rhuav tshem. Lawv tau teeb tsa kom ze rau ntawm qhov chaw uas cov hluav taws xob nkag mus hauv tsev. Cov neeg raug ntes, ua ib ntus, tiv thaiv cov khoom siv davhlau ya nyob twg. Lawv tau nruab nrog ze cov khoom siv kom muaj kev tiv thaiv.

Nrog nws cov khoom lag luam tsev neeg rau kev siv hluav taws xob thiab cov ntaub ntawv siv, LSP muaj cov khoom sib txuam tiv thaiv kom zoo. Lub chaw hloov chaw tso cai ua kom muaj nuj nqis-ua kom tiav kev tiv thaiv cov ntsiab lus rau txhua hom tsev thiab teeb tsa me me.
