Introduction to Zinc Oxide Arrester Characteristic Tester
TPYBL Zinc Oxide Arrester Characteristic Tester is a specialized instrument used for on-site and laboratory testing of various related electrical parameters of arresters. The instrument complies with the requirements of the power industry standard DL474.5-92 "Guidelines for On-site Insulation Tests - Arrester Tests". The Zinc Oxide Arrester Characteristic Tester 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. The Zinc Oxide Arrester Characteristic Tester features a large-screen LCD display, 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. The Zinc Oxide Arrester Characteristic Tester 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 (off-line testing) of zinc oxide arresters.
