Overview
The zinc oxide arrester comprehensive tester is a special instrument used to detect various related electrical parameters of the arrester on site and in the laboratory. It is widely used in on-site online monitoring (live testing) and laboratories of zinc oxide arresters. (Power outage maintenance) test. It complies with the essential techniques of the Electric Power Industry Standard of the People's Republic of China "
Implementation Guidelines for Field Insulation Tests and Lightning Arrester Tests". This instrument uses advanced technologies such as microcomputer sampling control to measure the full current, third harmonic resistive current, resistive current, peak capacitive current, active power, etc. of zinc oxide arresters under power frequency voltage. And display the voltage and current waveform and print out the test data. The use of large-screen LCD display with Chinese character menu prompts makes the human-machine exchange function stronger and provides on-site wiring 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 adopts an integrated design, making it easy to carry and work in the field.
