Product description
XHDD403 zinc oxide lightningarrester live tester with advanced
microcomputer as control component, fully intelligent operation, strong
anti-interference ability, accurate and reliable measurement, powerful
function, convenient operation, etc. It is the on-site and laboratory detection
of zinc oxide arrester exchanges. Ideal test instrument for electrical parameters.
Main features
1. This instrument adopts large-screen LCD display, Chinese/English character menu operation, easy to operate;
2. A variety of measurement methods, such as PT secondary method, laboratory measurement method, online current method and other measurement methods;
3. High-precision sampling and processing circuits, advanced Fourier harmonic analysis technology to ensure data reliability;
4. Thevoltage input has a 0.1A fuse, and there is an isolation transformer inside the instrument to completely isolate the instrument from the on-site PT. Double insurance ensures PT safety;
5. It has parameters such as the peak output of the resistive current fundamental wave, the angle between the fundamental current and the fundamental voltage, and the output parameters are stable, which is easy to judge the quality of the lightning arrester;
6. With edge correction function, it can eliminate the interference of live charging test;
7. The instrument comes with a rechargeable battery, which can work continuously for more than 3 hours without 220V AC.
8. Have a calendar clock, a micro printer;
9. Can store 1024 sets of measurement data;
10. Equipped with RS-232 communication port, the data can be uploaded to the computer for processing.
