METAG-9800 Remote phase tester Send email to us

The transmitter can judge whether the line is energized, measure the phase and frequency of the line, and send the measured data the host. After the host is synchronized by GPS, it measures simultaneously. The phase difference calculated by the two hosts is the phase difference of the two lines, and the same and phases of the two lines are judged.

The core of the instrument's measurement principle is the time difference of synchronous measurement by two hosts. The GPS timing is used synchronize the time of the two hosts, and the synchronization difference is less than 10 nanoseconds. The phase error introduced by this is less than 0. degree.

1. Phase difference accuracy: Error ≤ 5°.
2. Frequency accuracy: ±0.1HZ.
3. Voltage measurement range: 0～220kV.
4. The maximum transmission line of sight distance between the transmitter and the receiving host is about 100 meters.
5. The result judgment (in phase, out of phase) uses A-level standard, phase difference ≥ 30° is out of phase, difference < 30° is in phase.
6. The measuring distance between two GPS hosts is 300 meters to 800 kilometers.
7.atically switch GPS mode and timing mode according to the strength of the GPS signal.
8. Real-person voice prompts the measurement results and operation steps.
9. The 302*240 color screen displays the line phase difference, frequency, vector diagram, battery power, measurement time, longitude and latitude, satellite number, GPS signal strength other information at the same time.
10. Automatic shutdown after 1 hour of no operation.
11. Both the transmitter and the receiver are equipped with built- rechargeable lithium batteries, and the battery can be removed and replaced.
12. The battery capacity of the main unit is 2500mAH, and the capacity of the transmitter is 350mAH.
13. Leakage current < 10uA during high voltage measurement.
14. Transmitter working consumption < 0.1W, receiving host working consumption < 0.3W.
15. Working environment: -35℃---  45℃ Hum ≤ 95% RH.
16. Overall weight: about 11KG.
17. Instrument packaging size: length 89cm* 26cmm* height 11cm*2.
