Intelligent Zinc Oxide Surge Arrester Tester

Product Overview:

Intelligent Zinc Oxide Surge Arrester TesterThe lightning arrester tester is specifically designed to detect internal defects in poor electrical contact between MOA valves of gapless zinc oxide lightning arresters used in 10kV and below power systems. It measures the DC reference voltage (U1mA) of MOA and the leakage current at 0.75 U1mA.Intelligent Zinc Oxide Surge Arrester TesterIntegrating the DC high-voltage power supply, measurement, and control system into one unit, all components are concentrated in one chassis, which has the characteristics of small size and light weight. It is an essential equipment for on-site testing of power systems and zinc oxide lightning arrester production plants. Execution standard: DL/T848.1-2004.

Product Features
1. Fully automatic measurement, easy and fast operation
The precise closed-loop adjustment of 1mA current and 0.75 times DC reference voltage is carried out using the principle of automatic control. The measurement process is controlled by a microcomputer, and only one button is needed to automatically measure the DC reference voltage at 1mA and the leakage current at 0.75 times DC reference voltage of the zinc oxide arrester. The entire process only takes 15 seconds, making it very suitable for batch measurement.
2. Integrated structure, small size, light weight
This instrument integrates DC high-voltage power supply, measurement and control system, and all components are concentrated in one chassis, with the characteristics of small size and light weight
3. Special process design, simple wiring.
