Product Description

Zinc Oxide Arrester Tester

Darui Electric recommends:

The Zinc Oxide Arrester Tester is a specialized instrument used to detect the electrical performance of zinc oxide arresters. It is suitable for live or offline testing of zinc oxide arresters at various voltage levels, thereby promptly identifying 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 employs digital waveform analysis technology and uses software anti-interference methods such as harmonic analysis and digital filtering to ensure accurate and stable measurement results.

Instrument Overview

The Zinc Oxide Arrester Tester is a specialized instrument used for on-site and laboratory testing of various electrical parameters of arresters. It is widely used in on-site online monitoring (live testing) and laboratory (offline maintenance) testing of zinc oxide arresters. It complies with the requirements of the People's Republic of China electric power industry standard "DL/T987-2005 General Technical Conditions for Resistive Current Testers of Zinc Oxide Arresters". This instrument adopts advanced technologies such as microcomputer sampling and control. It can measure the total current, third harmonic, resistive current, resistive current peak, capacitive current, active power, etc. of zinc oxide arresters under power frequency voltage. It also displays voltage and current waveforms and prints output. It uses a large-screen liquid crystal display with Chinese menu prompts for operation, making the human-machine interaction more powerful. It also provides on-site wiring display. This instrument features simple wiring, high measurement accuracy, and strong reliability
