Grounding Resistance Tester Technical Principple

Grounding resistance testers feem ntau ntsuas kev tiv thaiv raws li lub hauv paus ntsiab lus ntawm qhov sib txawv. Thaum ntsuas, tam sim no raug txhaj rau hauv cov khoom siv hauv av los ntawm tus ntsuas, tsim kom muaj qhov sib txawv ntawm cov khoom siv hauv av thiab cov khoom siv hluav taws xob. Raws li Ohm txoj cai, qhov kev tiv thaiv hauv av yog sib npaug ntawm qhov sib txawv ntawm qhov sib txawv rau cov tshuaj tam sim no. Lub tester integrates ib tug meej tam sim no qhov chaw thiab voltage ntsuas Circuit Court, ua kom nws mus rau qhov tseeb ntsuas feeb muaj peev xwm sib txawv thiab tam sim no qhov tseem ceeb, yog li xam tus nqi tseeb ntawm lub grounding kuj.
