Product Description

GDYZ-301A Zinc Oxide Surge Arrester Tester

General introduction

GDYZ-301A Automatic Zinc Oxide Surge Arrester Tester contains below three functions:

Resistive current test;
Current meter calibration of monitor;
Counter action test of monitor.
It is the special equipment of testing zinc oxide electric performance. The instrument can accurately and stably measure the arrester resistive current and the monitor counter action parameters while the equipment is running. It can also check the monitor ammeter. 



Features
1. 8-inch color LCD touch screen, high speed thermal printer.
2. The measurement data of wire and wireless is the same.
3. Wireless sampling, with long distance.
   A. Wired: indoor use, or onsite where the PT sampling wiring cabinet is near with tested lightning arrester.
   B. Wireless: outdoor use, or onsite where the PT sampling wiring cabinet is far from tested lightning arrester, wireless distance is up to 1000M.
4. Three-phase can be measured at the same time. The resistive current of 3 channels can be measured at the same time, meanwhile, there are two interference modes, 1) no interference: the inter-phase angle cannot be calculated and corrected automatically under this mode;2) With interference: the inter-phase interference angle can be calculated and corrected. Only one time connection to finish measurement of ABC phase.
5. Built-in high capacity Li-battery, suitable for no power supply field.
