Profile:

The KDYZ-301 is a dedicated instrument for testing the electrical performance of zinc oxide (ZnO) lightning arresters. It uses an industrial control computer to analyze total current, resistive current and its harmonics, power frequency reference voltage, active power, and phase difference. With an 800×480 color touchscreen and built-in thermal printer, it provides clear waveform visualization and on-site report generation. It supports both AC220V power and a 12V 10000mAh lithium battery for >4 hours of continuous operation, making it suitable for both lab and field use.

Features:

Supports wired (40m, expandable) and wireless (400m, expandable up to 2000m) PT signal transmission.
Offers multiple voltage reference sampling methods: wired, wireless, induction plate, and no-voltage reference.
Isolated current and voltage sensors ensure safe and reliable operation.
Performs anti-interference calculations to compensate for phase differences in A/C phase currents.
High-speed sampling and digital signal processing deliver exceptional measurement accuracy.
Rugged, dustproof, waterproof, and corrosion-resistant plastic enclosure for portability.
Supports continuous testing with real-time voltage/current curve display and quick printing.
Can test A, B, and C three-phase arresters in sequence and save data as a single group.
Runs on Windows OS with USB data export and external mouse/keyboard support.
Stores large amounts of test data on an internal SD card with data management functions.
