ES9020 Intelligent Lightning Protection Component Tester
Introduction
Product Overview
Also known as a lightning protection component tester or SPD field tester, this instrument is specially designed for performance testing of lightning arresters, surge protectors, varistors, cermet discharge tubes, and direct-air lightning arresters.
Key Features
The instrument features a built-in charging function for offline use, overcoming the shortcomings of traditional products that require a power outlet and are inconvenient for on-site operation. With a voltage output of up to 2000 V, it offers a wider application range. It incorporates high-voltage short-circuit protection and automatic discharge functions, making the instrument reliable, safe, and durable.
Additionally, it features a luxurious large color screen display and offers functions such as data storage, data review, pass/fail judgment, automatic shutdown, and USB data upload. The instrument boasts an elegant appearance, wide measurement range, high resolution, convenient operation, easy portability, accuracy, reliability, stable performance, and strong anti-interference capability.
Environmental Adaptability
Moreover, it has an anti-vibration, dust-proof, and moisture-proof structure, making it adaptable to harsh working environments. It is an indispensable instrument for meteorological lightning protection, electric power, post and telecommunications, communications, electromechanical installation and maintenance, and industrial enterprises that use electricity as industrial power or energy. It is suitable for measuring performance parameters of various arresters and surge protectors.
Technical Specifications
The intelligent lightning protection component tester is constructed using medium and large-scale integrated circuits. This instrument features high output power. The initial operating voltage measurement range is 10 V to 2000 V, and the leakage current measurement range is 0.1 μA to 199.9 μA.
