HYG-8800 Satellite High Voltage Wireless Voice Core Phase Meter

The HYG-8800 satellite high-voltage wireless voice phase detector is used to check whether the high-voltage phase is in the same phase and whether the phase sequence color is correctly labeled for long distance (300-800 km apart). It can also be used for close-range grid connection or loop phase checking. The instrument is suitable for live operation of 1V ~ 220KV transmission line and secondary side live operation, and has high voltage electricity test function.

Product Introduction

HYG-8800 Satellite High Voltage Wireless Voice Core Phase Meter (hereinafter referred to as "Instrument") is used to check whether the high voltage phase is in phase and whether the phase sequence color is correctly labeled at a long distance (300-800 km apart). It can also be used for close-range grid connection or loop phase checking. The instrument is suitable for live operation of 1V ~ 220KV transmission line and secondary side live operation, and has high voltage electricity test function.

The instrument adopts wireless transmission technology, which is safe and reliable to operate and easy to use. It overcomes many shortcomings of wired phase detector. The instrument uses GPS timing technology, and two (or more) instruments can be separated by several hundred kilometers of nuclear phase.
Product parameters

7. Automatically switch between GPS mode and timing mode according to the strength of GPS signal.

8. Measurement results and operation steps of human voice prompt.

9. 302 *240 color screen simultaneously displays the information of line phase difference, frequency, loss plot, battery power, measurement time, longitude and latitude, satellite number, GPS signal intensity and so on.

10. Automatic shutdown without operation for 1 hour.

11. Both transmitter and receiver have built-in rechargeable lithium batteries, and the batteries can be disassembled and replaced.

12. The main battery capacity is 2500mAH and the launcher battery capacity is 350mAH.

13. Leakage current < 10uA in high voltage measurement.

15. Working environment: - 35 ~45 ~95% RH.

16. Storage environment: - 40 55 humidity < 95% RH.

17. Whole machine weight: about 11 KG.

18. Instrument packaging size: length 89cm * width 26cmm * height 11cm * 2.
Product features

The transmitter can judge whether the line is live or not, measure the phase and frequency of the line, and send the measured data to the host computer. The host computer measures the phase difference between the two hosts at the same time after being given time by GPS. The phase difference between the two hosts is calculated as the phase difference between the two lines to judge the similarity and dissimilarity of the two lines.

The core of the principle of instrument measurement is the time difference of synchronous measurement between two mainframes. GPS timing is used to synchronize the time of two mainframes, and the synchronous difference is less than 10 nanoseconds. The phase error introduced is less than 0.1 degree.
