Product characteristics
1.800 ×480 color LCD touch screen, high-speed thermal printer; Graphic display, easy to operate and use on-site personnel.
2. Wireless transmission of PT signals over 400 meters, on-demand configuration can reach 2000 meters, can meet the needs of various experimental sites.
3. Suitable for lightning arrester live, power failure or laboratory and other places to use.
4. A variety of voltage reference signal sampling methods: not only to meet the 6-35kV zinc oxide arrester field live test can also be used for 35-750KV live operation, with induction board, Bluetooth function.
5. Wired synchronization: the signal is taken from the PT end metering winding, and the digital signal is transmitted wired.
6. Wireless synchronization: the signal is taken from the PT end metering winding, and the digital signal is transmitted wirelessly, eliminating the long distance connection of the cable.
7. Induction board synchronization: do not need to take signals from the PT terminal, install induction board from the zinc oxide arrester B phase base to take voltage signals.
8. No voltage synchronization: It does not need to obtain signals from the PT terminal, and uses software calculation to find the voltage reference.
9. Voltage and current signals (input impedance less than 1Ω) are isolated to ensure data reliability and security.
10. It has three channel resistive current measurement at the same time and provides two anti-interference modes at the same time.
1 No interference: In this mode, the instrument will not automatically correct the interphase interference Angle when measuring;
2 Interference: In this mode, the instrument measurement will automatically calculate and correct the interference Angle between phases, and the measurement of ABC three-phase can be completed at the same time with only one connection.
11. Real three-phase current, three-phase voltage test at the same time, automatic calculation without compensation, improve work efficiency; There is only weak current inside the instrument, and the voltage does not exceed 12V; Current and voltage sensors are isolated, safe and reliable.
12. Support wired synchronization, wireless synchronization two voltage reference signal sampling methods; It also supports the non-voltage mode. The voltage reference can be found through software calculation, and the three-phase or B-phase voltage reference can be used as the voltage reference.
