Cov txiaj ntsig: Muaj kev sib npaug zoo ntawm cov nqi-ua hauj lwm zoo thiab hluav taws xob conductivity. Nws yog sib dua hauv qhov hnyav piv rau tus tooj liab, uas tuaj yeem ua tau zoo hauv qee cov ntawv thov.

Qhov tsis zoo: Nquag rau corrosion thiab tau qis dua li tooj liab. Nws kuj tseem xav tau kev tiv thaiv kev tiv thaiv ntxiv los tiv thaiv oxidation.

Cov Ntawv Thov: Siv nyob rau hauv lub hwj huam kis kab sib kis cov kab, transformers, thiab lub zog cua tshuab qhov hnyav uas hnyav thiab tus nqi yuav txiav txim siab.
