Zinc Oxide Lightning Arrester Resistive Current Tester

I.Preface

Zinc oxide arrester resistance current tester is a special instrument designed for live detection of metal oxide arrester in power system. It can measure the ac leakage parameters of the equipment in the running state, so as to timely find out the dangerous defects such as moisture in the internal insulation of the equipment and the aging valve plate. By accurately sampling the voltage and current signals of the measured equipment, the instrument USES anti-interference methods such as Fourier transform technology, harmonic analysis and digital filtering to make the measurement results accurate and reliable.

II.Performance Feature

1. Fully automatic instrument, the three-phase data can be measured at the same time with one connection, or single-phase data can be measured separately;

2. With the function of harmonic analysis, can accurately analyze the content of the third, fifth and seventh harmonics;

3. Anti-interference function to ensure accurate and reliable data;

4. 8.0-inch color touch LCD, which can display three-phase data and waveform at the same time;

5. Dual use of alternating and direct, built-in large-capacity lithium ion battery, which can work for about 6 hours in a single charge;

6. Wired, wireless and pt-free measurement methods support 220V power supply signal acquisition;

7. Bluetooth communication, RS232 serial communication (either one can be equipped with software program to control instrument, test or upload data and save data through tablet or mobile phone);

8. Wireless data transmission saves the tedious long-distance connection of voltage measuring wire and reduces labor intensity;

9. Humanized menu design, human-machine interface friendly, easy to operate;

10. Storage function: the instrument can save 200 sets of test data, and the saved data can be exported by U disk;

11. Small size, light weight, easy to carry, suitable for field operations.
