I. Product Overview

The KDYZ-205 Zinc Oxide Arrester Resistive Current Tester is a specialized instrument for detecting the electrical performance of zinc oxide arresters. This instrument is suitable for live or offline testing of zinc oxide arresters at various voltage levels, thereby promptly identifying hazardous defects such as internal insulation moisture and valve plate aging.

The instrument is simple to operate and easy 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 utilizes digital waveform analysis technology, employing software anti-interference methods such as harmonic analysis and digital filtering to ensure accurate and stable measurement results. It can accurately analyze the content of the fundamental wave and the 3rd to 7th harmonics, and can overcome the influence of inter-phase interference to correctly measure the resistive current of side-phase arresters. This device is equipped with a high-speed panel-mounted printer.
