YBL-III Type Zinc Oxide Surge Arrester TesterDetailed product description：

The YBL-III type zinc oxide lightning arrester tester is a specialized instrument used to detect various electrical parameters of zinc oxide lightning arresters. It is widely used for online monitoring (live testing) and laboratory (power-off maintenance) testing of zinc oxide lightning arresters. Meet the technical requirements of the People's Republic of China power industry standard "DL474.5-92 Implementation Guidelines for On site Insulation Test - Surge Arrester Test".

The zinc oxide lightning arrester tester adopts microcomputer sampling and control technology, which can measure the full current, third harmonic, resistive current, peak resistive current, capacitive current, active power, etc. under the power frequency voltage of the zinc oxide lightning arrester; And display the waveforms of voltage and current; Print the test results.
This instrument adopts a large screen LCD display, Chinese character menu prompts for operation, and can provide on-site wiring display, making human-machine exchange function stronger. This instrument has the characteristics of simple wiring, high measurement accuracy, and strong reliability.
