GDYZ-302 Wireless Zinc Oxide Surge Arrester Tester
GDYZ-302 Zinc Oxide Arrester Live Tester is a special instrument used to test the electrical performance of Zinc Oxide Arrester. It is suitable for live or power-off detection of Zinc Oxide Arrester of various voltage levels, so that to found dangerous defects such as dampness of internal insulation and aging of valve plates in time.
The instrument is simple to operate and easy to use. The entire measurement process is controlled by an industrial computer. It can measure the full current, resistive current and its harmonics, power frequency reference voltage and harmonics, active power and phase difference. Displays true waveforms of voltage and current. The instrument uses digital waveform analysis technology and software anti-interference methods such as harmonic analysis and digital filtering to make the measurement results accurate and stable. It can accurately analyze the content of the fundamental wave and the third to seventh harmonic, and can overcome the influence of inter-phase interference. Measure the resistive current of the side-phase arrester.
● 800 *480 color LCD touch screen, high-speed thermal printer; graphics and text display, intuitive interface, easy for field personnel to operate and use.
● Wireless transmission of PT signal is over 400 meters, which can reach 2000 meters on demand.
● It is suitable for live arrester, power off arrester or laboratory test.
● Really achieve three-phase current and three-phase voltage measurements at the same time, improve work efficiency; the instrument only has weak internal current, voltage does not exceed 12V; current and voltage sensors are completely isolated, safe and reliable.
● The leakage current of zinc oxide arrester can also be measured without counter, which completely solves the test problem of 6 ~ 10KV arrester.
