I. Product Overview:
       The KEYHX-A Zinc Oxide Arrester Characteristic Tester (Zinc Oxide Arrester Resistive Current Tester) is a specialized instrument for on-site and laboratory testing of various electrical parameters of arresters. It is widely used for on-site online monitoring (live testing) and laboratory (power-off testing) of zinc oxide arresters. Complies with the requirements of the power industry standard "DL474.5-92 Field Insulation Test Implementation Guide - Arrester Tests".
       This tester uses advanced technologies such as microcomputer sampling and control, capable of measuring the full current, third harmonic, resistive current, peak resistive current, capacitive current, active power, etc., of zinc oxide arresters under power frequency voltage. It also displays voltage and current waveforms and supports print output. Equipped with a large LCD screen and Chinese menu prompts for operation, it enhances human-machine interaction. Additionally, it provides on-site wiring display. This instrument features simple wiring, high measurement accuracy, and strong reliability.
