TAG-8600C 500kV Wireless High Voltage Phase Detector for Substations & Power

The TAG-8600C Wireless High Voltage Phase Detector (hereinafter referred to as "the instrument") is used for phase verification during grid connection or ring network connection of two high-voltage lines. It is applicable to phase verification of 5V～500kV AC transmission lines and secondary live display devices, and is also equipped with a line live detection function.

Adopting wireless transmission technology, the instrument features safe and reliable operation as well as convenient use, eliminating multiple drawbacks of wired phase detectors. In addition, it supports upgraded functions including phase sequence detection and remote phase verification.

The instrument consists of 2 transmitters and 1 receiving host. The transmitters can judge whether the line is live and measure the phase and frequency of the line. During short-range phase detection, the X and Y transmitters send measured data to the receiving host via radio signals. The receiving host calculates the phase difference between the two lines based on the data and judges in-phase or out-of-phase status.

1. Phase difference accuracy: Error ≤ 5°
2. Frequency accuracy: ±0.1Hz
3. Cross-voltage measurement range: 5V～500kV
4. Maximum visual transmission distance between transmitter and receiving host: about 100 meters
5. Human voice prompt for measurement results and operation steps
6. 3.2-inch color screen, simultaneously displaying phase difference, frequency, vector diagram and in-phase/out-of-phase results of two lines
7. Auto power-off after 1 hour of inactivity
8. Both transmitters and receiving host are built-in with rechargeable lithium batteries, equipped with 5V chargers
9. Built-in 18650 lithium battery for the host with a capacity of 2600mAh; Built-in 10440 lithium battery for the transmitter with a capacity of 340mAh. (Due to different battery batches, slight capacity deviations may exist, subject to the actual product.)
10. Leakage current during high voltage measurement: ＜10μA
11. Operating power consumption: Transmitter ＜0.1W, Receiving host ＜0.3W
12. Working environment: Temperature -35℃ ~ +45℃, Humidity ≤95%RH
13. Overall weight: Approximately 7KG
14. Product packaging dimensions: 112cm (length) × 26cm (width) × 11cm 

15. Result judgment adopts the national standard Grade A, with 30° as the threshold for in-phase and out-of-phase judgment.

    When the phase difference ≥ ±30°, it is judged as out-of-phase. The voice prompt plays "Out-of-phase", the screen displays "Out-of-phase", and the out-of-phase indicator light turns on.

    When the phase difference ＜ ±30°, it is judged as in-phase. The voice prompt plays "In-phase", the screen displays "In-phase", and the in-phase indicator light turns on.

    All phase difference results take the X circuit as the reference. The angle value indicates the phase of Y leading X.

    Example: X=0°, Y=240°, the difference = Y leads X by 120°.

    Notice:

    If the frequencies of the two lines are inconsistent, a quasi-synchronization paralleling device shall be used to control the frequency and phase of the generator. Grid connection and power transmission are allowed only after the generator phase and frequency are consistent with those of the main power grid.
