I. Product Overview

KDYZ-205 Zinc Oxide Arrester Resistive Current Tester is a special instrument used to detect the electrical performance of zinc oxide arresters. This instrument is suitable for live or outage detection of zinc oxide arresters of various voltage levels, thereby timely discovering dangerous defects such as internal insulation moisture and valve plate aging.

The instrument is simple to operate and convenient to use. The entire measurement process is controlled by a microcontroller. It can measure the total current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power, and phase difference of zinc oxide arresters. The large screen can display the real waveforms of voltage and current. The instrument uses digital waveform analysis technology, adopting software anti-interference methods such as harmonic analysis and digital filtering to make measurement results accurate and stable. It can accurately analyze the content of the fundamental wave and 3rd to 7th harmonics, and can overcome the influence of interphase interference to correctly measure the resistive current of side-phase arresters. This device is equipped with a high-speed panel printer.
