Ib qho zoo hauv av kom ntseeg tau tias kev ua haujlwm zoo sib xws.
Cov hluav taws xob zoo li qub yog tsim los ntawm kev sib txhuam ntawm cov khoom sib txawv thiab muaj dav nyob rau hauv qhov xwm txheej, kev tsim khoom, thiab tib neeg lub neej txhua hnub. Raws li cov khoom siv hluav taws xob tau dhau los ua rhiab heev, lub hauv paus system, raws li kev tiv thaiv tseem ceeb tshaj plaws hauv kev tsim hluav taws xob, cuam tshuam ncaj qha rau kev tiv thaiv - zoo li kev tswj hwm ntawm tag nrho cov lag luam hluav taws xob. Lub hauv paus tsis zoo tsis tuaj yeem ua kom muaj peev xwm sib npaug thoob plaws txhua qhov chaw ua haujlwm hluav taws xob, yooj yim ua rau electrostatic paug. Hauv kev txhim kho kev lag luam tes hauj lwm, cov ntsiab lus tseem ceeb -chav computer- ua lub luag haujlwm tseem ceeb, thiab nws qhov kev tsim kho thiab kev khiav hauj lwm ib puag ncig tau ntev los ua kom pom tseeb. Tshwj xeeb, ntau chav khoos phis tawj, vim yog kev tsim kho tsis raug, raug kev puas tsuaj los ntawm kev cuam tshuam sab nraud (xws li xob laim, hluav taws xob zoo li qub, overcurrent, thiab overvoltage), ua rau muaj kev cuam tshuam hauv network thiab kaw, thiab hauv qhov xwm txheej hnyav, txawm tias hlawv tawm cov tshuab thiab ua rau tus kheej raug mob lossis tuag. Grounding txuas ib qho taw tes hauv Circuit Court lossis hlau casing rau lub ntiaj teb nrog tus neeg xyuas pib, aiming los pab txhawb qhov ntws ntawm cov av tam sim no. Yog li ntawd, qhov qis dua cov av tiv thaiv, qhov yooj yim dua nws yog rau cov av tam sim no ntws. Ntxiv nrog rau kev siv lub tshuab computer hauv av, nws kuj tseem tsim nyog kom txo qis qhov muaj peev xwm hloov pauv uas ua rau muaj suab nrov. Yog li ntawd, qhov qis dua grounding kuj, qhov zoo dua.
Dhau li ntawm electrostatic grounding, peb kuj tuaj yeem tiv thaiv hluav taws xob zoo li qub los ntawm peb tus kheej ua. Piv txwv li, thaum nkag mus rau hauv chav computer, peb tuaj yeem hnav khaub ncaws ua haujlwm zoo li qub lossis tiv thaiv- khaub ncaws zoo li qub. Anti- cov khaub ncaws zoo li qub yog ua los ntawm kev tiv thaiv- zoo li qub thiab plua plav- cov ntaub ntawv pov thawj (feem ntau hu ua cov kab xev hluav taws xob), uas yog woven los ntawm polyester tshwj xeeb filaments thiab siab -kev ua tau zoo mus tas li conductive fibers siv cov txheej txheem tshwj xeeb. Lawv muaj qhov ua tau zoo thiab ntev -tiv thaiv- zoo li qub thiab plua plav- pov thawj ua haujlwm thiab tuaj yeem tso cov nqi zoo li qub los ntawm tib neeg lub cev.
