Product Introduction of Metal Oxide Zinc Oxide Arrester Live Tester
TPYBL Zinc Oxide Arrester Characteristic Tester is a special instrument used for on-site and laboratory testing of various related electrical parameters of arresters. The instrument complies with the requirements of the electric power industry standard DL474.5-92 "Guidelines for On-site Insulation Tests - Arrester Tests". It adopts advanced technologies such as microcomputer sampling and control, and 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 features a large-screen LCD display and Chinese menu prompts for operation, enhancing human-machine interaction. It also provides display of voltage and current waveforms at the test site and can print output. This instrument has the characteristics of simple wiring, high measurement accuracy, and strong reliability, and is widely used in on-site online monitoring (live testing) and laboratory (outage testing) of zinc oxide arresters.
