Zinc oxide arrester live tester

Type: ZC-710B
       The zinc oxide surge arrester is an electrical product used to protect various electrical equipment in the power system from overvoltage damage and has good protection performance. In order to check whether the performance of the zinc oxide arrester is normal, we have developed a zinc oxide arrester tester, which is a special instrument for on-site and laboratory detection of various electrical parameters of the arrester. It is widely used in the field of zinc oxide arrester. Monitoring (live testing) and laboratory (blackout maintenance) testing.
       The wireless transmission of the voltage measurement signal avoids the trouble of laying a long-distance voltage measurement line due to the distance between the arrester and the PT.
       The device adopts large-screen color LCD display, full Chinese menu prompt operation and printout. Make the human-machine exchange function stronger. The instrument has the characteristics of simple wiring, high measurement accuracy and high reliability. .
