Product description zinc oxide lightning arrester live tester is a special instrument for on-site and laboratory detection of various electrical parameters of lightning arresters. It is widely used in on-site online monitoring (charge test) and laboratory (blackout maintenance) testing of zinc oxide arresters. It conforms to the requirements of the People's Republic of China power industry standard "DL474.5-92 Field Insulation Test Implementation Guide - Arrester Test". The instrument adopts microcomputer to carry out sampling, control and other advanced technologies, and can measure the full current, third harmonic, resistive current, resistive current peak, capacitive current, active power of the zinc oxide arrester under the power frequency voltage. It also displays voltage and current waveforms and printout test data. The large-screen LCD and the Chinese/English character menu prompt operation make the user interfacecomfortable, and at the same time provide the on-site waveform display. The instrument has the characteristics of simple wiring, high measurement accuracy and high reliability. The instrument is small in size and light in weight, and has an integrated design for easy carrying and field work. Main features
This instrument adopts 800×480 dot matrix 65K truely colorful large-screen LCD, Chinese/English menu operation, easy to use, and the display data is clear to see and easy to read.
High-precision sampling and processing circuits, advanced Fourier harmonic analysis technology, which can make datamore reliable.
The instrument uses a unique high-precision sensor to directly collect the input voltage and current signals.
With harmonictest function, can measuresingle or three phase at the same time.
