HZ-20A-I Handheld Surge Arrester Characteristics Test Set

I.Overview

Handheld zinc oxide arrester tester is a special instrument used for field and laboratory testing of various electrical parameters of arresters. This instrument adopts advanced technologies such as microcomputer sampling and control, and can measure the full current, third harmonic, resistive current, resistive current peak value, capacitive current, active power, etc. of zinc oxide arrester under power frequency voltage. And display voltage, current waveform and print out test data. Using large-screen LCD display, Chinese characters menu prompts operation, making the man-machine exchange function stronger, and at the same time providing on-site waveform display. The instrument has the characteristics of simple wiring, high measurement accuracy and strong reliability. The instrument is small in size, light in weight, and adopts an integrated design, which is easy to carry and operate in the field.
