OEM Best ultrasonic testing instrument Supplier – GDYZ-301A Zinc Oxide Surge Arrester Tester – HV Hipot Detail:

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

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