Overview of KDYZ-201 Zinc Oxide Arrester Live Tester:
1. The instrument is not equipped with a high-energy lithium-ion battery as standard; it can be optionally built-in.
2. 5.7-inch 320×240 LCD display, high-speed thermal printer; graphical display, intuitive interface, convenient for field personnel to operate and use.
3. Suitable for use in live, de-energized, or laboratory environments for arresters.
4. Current and voltage sensors are fully isolated, safe and reliable. Testing A, B, C three-phase zinc oxide arresters in three separate tests can be saved as one set of test data.
5. The instrument can perform continuous testing, display voltage and current curves, and quickly print data and curves.
6. Built-in memory can store 200 sets of test data even when power is off.
7. Optional RS232 communication interface allows testing via a host computer and exporting test data.
8. Anti-interference calculation can compensate for the deviation of A and C phase currents caused by B phase.
9. High sampling frequency and advanced digital signal processing technology provide strong anti-interference performance and extremely high measurement accuracy.
10. Optional built-in high-energy lithium-ion battery is especially suitable for places without power supply. The instrument only carries low voltage internally, not exceeding 12V, and can work even while charging.
11. Adopts dustproof, waterproof, and anti-corrosion engineering plastic sealed box, small size, light weight, easy to carry.
