1. Ua ntej, xyuas seb qhov kev ua tau zoo ntawm zinc oxide ntes tester yog qhov qub tom qab cov khoom siv tau qhib, tsis muaj qhov txawv txav, thiab lub zog txaus;
2. Txheeb xyuas seb qhov chaw ntawm cov khoom puas yog qhuav thiab huv si, thiab seb lub hwj chim qaum, txuas cable thiab av xaim puas zoo;
3. Tom qab txuas cov av hauv av ntawm cov khoom siv mus rau qhov chaw nres nkoj hauv av ntawm lub thawv high-voltage, cov xaim hauv av los ntawm qhov chaw nres nkoj hauv av ntawm lub thawv high-voltage yog ruaj khov rau hauv av network, thiab cov xaim xaim raug coj tawm. Tom qab ntawd txuas lub ntsuas thiab tswj lub thawv thiab lub thawv high-voltage nrog rau cov kab txuas txuas.
4. Qhov qis kawg ntawm cov khoom kuaj yog txuas nrog "cov khoom kuaj" kawg ntawm lub thawv high-voltage, thiab lub siab kawg yog txuas nrog lub siab-voltage kawg ntawm lub thawv high-voltage;
5. Lub high-voltage lead hlau yuav tsum yog ib tug hlau nrog ib tug insulating sheath kom txo tau corona tam sim no ntawm high-voltage lead hlau rau hauv av, thiab xyuam xim rau hauv av rwb thaiv tsev.
6. Tom qab kev ntsuam xyuas, nco ntsoov rov pib dua qhov voltage thiab ntxhib hloov khawm ntawm zinc oxide ntes tester rau xoom, tua hluav taws xob siab, thiab tom qab lub teeb ntsuab qhib, dai cov av xaim ntawm qhov kawg ntawm qhov hluav taws xob siab, thiab Thaum kawg tso cov high voltage kawg los yog hloov cov qauv kuaj.
