Intelligent Lightning Protection Component Tester

I.Introduction

Intelligent lightning protection component tester is a special instrument used for performance testing of lightning arresters, lightning protection devices, surge protectors, varistors, cermet discharge tubes, and straight air lightning arresters. This instrument uses the charging function offline to overcome the shortcomings of traditional products that it is inconvenient to use on-site operation. The voltage output of 2000V is more widely used, the use of high-voltage short-circuit protection, automatic discharge function, and the instrument is reliable, safe and durable. At the same time, it adopts functions such as luxurious large-color screen display, data storage, data review, qualification judgment, automatic shutdown, and USB data upload. The whole machine is beautiful and high-grade, wide range, high resolution, easy to operate, easy to carry, accurate, reliable, stable performance, strong anti-interference ability.

ES9020 also has a shock-proof, dust-proof, and moisture-proof structure to adapt to harsh working environments. It is a commonly used and indispensable instrument for meteorological lightning protection, electric power, post and telecommunications, communications, electromechanical installation and maintenance, and industrial enterprises that use electric power as industrial power or energy. . It is suitable for testing the performance parameters of various lightning arresters and surge protectors.

ES9020 intelligent lightning protection component tester is composed of medium and large-scale integrated circuits. The output power of this watch is large, the measuring range of initial operating voltage: 10-2000V, the measuring range of leakage current: 0.1~199.9uA, the repeatability is good, and the one-key measurement is convenient and quick.
