GDYZ-302 Wireless Zinc Oxide Surge Arrester Tester
● 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.
● It supports both wired synchronization and wireless synchronization for voltage reference signal sampling, and also supports non-voltage mode for finding voltage reference through software calculation.
● With high performance and large capacity lithium-ion batteries, it is especially suitable for power-free applications.
● The instrument adopts embedded hardware platform and embedded operating system, which can expand audio and video playing function and game entertainment function.
● The instrument can be switched on and off at any time, which is more stable than the instrument based on industrial computer, and is not easy to crash and collapse.
● Software functions can be expanded anytime, anywhere according to customer requirements.
● It is equipped with a USB interface to support U-disk data export. It can be used with USB mouse and keyboard, and it is easy to operate.
● The SD card with 4 GB capacity can store a large amount of test data, and has the functions of data management and storage.
● Supporting PC management software, with historical data management, data analysis, report printing and other functions.
● High-speed sampling frequency, advanced digital signal processing technology, strong anti-interference performance, high accuracy of measurement results.
● Dust-proof, waterproof and anti-corrosion engineering plastic sealed box is adopted, which is small in size, light in weight and easy to carry.
