I. Overview

 Wireless Zinc Oxide Arrester Tester is a special instrument for on-site and laboratory detection of lightning arrester’s electrical parameters, widely used in on-line monitoring of zinc oxide surge arresters (online test) and laboratory (offline maintenance) test. Meet the People's Republic of China power industry standard "DL474.5-92 field insulation test implementation guidelines - arrester test" to the surgery. The instrument uses microcomputers for sampling, control and other advanced technologies to measure the full current, third harmonic, resistive current, resistive current peak, capacitive current, active power, etc. of zinc oxide surge arresters at power frequency voltages. And display the voltage, current waveform and printout test data. Large-screen liquid crystal display, English menu prompt operation, so that the human-machine exchange function is stronger, while providing on-site waveform display. This instrument has the characteristics of simple wiring, high measurement accuracy, and strong reliability. The instrument is small in size, light in weight, and has an integrated design for easy carrying and field operations.
