1、 Overview:

DYBL-601 Zinc Oxide Arrester Resistive Current Tester is a special instrument used for on-site and laboratory testing of various electrical parameters related to the arrester, which is widely used in on-site online monitoring (live testing) and laboratory (power outage maintenance) testing of zinc oxide arrester. It conforms to the key techniques of the electric power industry standard of the People's Republic of China, DL474.5-92 Guidelines for the Implementation of Field Insulation Test - Arrester Test. The instrument adopts advanced technologies such as microcomputer for sampling and control, and can measure the full current, third harmonic, resistive current, peak resistive current, capacitive current, active power, etc. of zinc oxide arrester under power frequency voltage. The waveform and printout of voltage and current are displayed. Large screen LCD display and Chinese menu prompt operation are adopted to make man-machine exchange function stronger. At the same time, field wiring display shall be provided. The instrument has the characteristics of simple wiring, high measurement accuracy and strong reliability.
