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