Product Introduction
The Lightning Protection Component Tester is an instrument designed for testing the DC parameters of overvoltage protection components such as zinc oxide arresters (zinc oxide varistors and metal oxide varistors). It features memory, calculation, hold, self-check, and leakage alarm functions. Equipped with high-voltage short-circuit protection, overcurrent protection, and high-voltage preset capabilities, its high-voltage self-discharge time is less than 5 seconds. Test results are displayed on two 3½-digit LCD screens—one showing voltage values and the other current values—ensuring high accuracy and reliability. It can also function as an adjustable DC high-voltage source (1kV～10kV) with output current ≤1mA. This intelligent lightning protection component tester is suitable for testing DC parameters of zinc oxide arresters (varistors), ceramic-metal two/three-electrode discharge tubes, vacuum arresters, and other overvoltage protection components.
Product Features
☆ Suitable for measuring DC parameters of overvoltage protection components such as zinc oxide arresters (varistors), ceramic-metal two/three-electrode discharge tubes, and vacuum arresters. It can also serve as a voltage-stabilized or constant-current power supply for other applications;
☆ Features high-voltage short-circuit protection, overcurrent protection, high-voltage preset, and range adjustment functions. High-voltage self-discharge time is less than 0.5 seconds;
☆ Includes self-check functionality;
☆ Measurement data is displayed on a three-and-a-half-digit LCD screen with high accuracy and reliability;
☆ Allows preset range selection during measurement and provides audible alerts for out-of-range tests, making it suitable for component grouping and inspection;
☆ Supports continuous measurement for uninterrupted batch testing;
☆ Simple panel functions for ease of operation;
☆ Lightweight and portable;
