Product Description

 

Product Overview
 

Kdyz-201 zinc oxide arrester live tester is a special instrument used to test the electrical performance of zinc oxide arresters. This instrument is applicable to the live or power-off test of zinc oxide arresters of various voltage levels, so as to timely find out the dangerous defects such as internal insulation damp and valve aging.
 

The instrument is simple to operate and easy to use. The whole measuring process is controlled by a microcomputer. It can measure the full current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference of zinc oxide arrester.

The large screen can display the real waveform of voltage and current. The instrument uses digital waveform analysis technology and software anti-interference methods such as harmonic analysis and digital filtering to make the measurement results accurate and stable. It can accurately analyze the content of fundamental wave and 3rd ~ 7th harmonic, overcome the influence of phase to phase interference, and correctly measure the resistive current of side phase arrester.
