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 3?-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.
