Product Features
Working Principle
The instrument consists of two transmitters (X and Y) and a receiver. The two transmitters can determine whether the line is charged and launch a phase signal. The receiving meter collects signals from both transmitters to determine whether the phase sequences on both sides are the same.
Security Matters
1.The insulating rod should undergo a voltage withstand test before use.
2.The standard length of the insulating rod is 3 m, suitable for voltages up to 220 kV. If the circuit voltage exceeds 220 kV, please use an insulating rod longer than 3 meters.
3.The operator's hand position should not exceed the handle position of the insulating rod.
Technical Characteristics
1.Accuracy: When the phase sequence is the same, the error is ≤ 5°.
2.Frequency accuracy: ±0.1 Hz.
3.Measuring voltage range: 0.22 to 220 kV.
4.The transmission distance between the transmitter and the receiving host is more than 130 meters; the maximum distance between the two transmitters is about 260 meters.
5.Results (in phase, out of phase) are based on a standard: a phase difference of ≥ 30° indicates out of phase, while a phase difference of < 30° indicates in phase.
6.Voice prompts include a male voice saying "in phase" and a female voice saying "phase out."
7.The screen simultaneously displays the phase difference, frequency, waveform, and vector diagram for the two lines.
8.The host indicates battery status and has an automatic shutdown feature after half an hour of inactivity.
9.Both the two transmitters and the receiver use rechargeable lithium batteries.
10.A high-pressure test report is available, confirming the function of the phase sequence.
11.During high-pressure measurements, the leakage current is < 10 µA.
12.Transmitter power consumption is < 0.1 W; the receiving host's power consumption is < 0.3 W.
13.The host's lithium battery capacity is approximately 2200 mAh, while the transmitter battery capacity is about 350 mAh.
14.Working environment: temperature -35 °C to +45 °C; humidity ≤ 95% RH.
15.Storage conditions: temperature -40 °C to +55 °C; humidity ≤ 95% RH.
16.Weight: approximately 5 kg.
17.Instrument package dimensions: 71 cm long, 26 cm wide, and 11 cm high.

Instruments To Check
| Check the project | Check the method | Normal phenomenon | Abnormal phenomenon | Exception handling |
|---|---|---|---|---|
| Insulating rod pressure | Check pressure performance reference appendix A | Leakage current is less than 10 uA | Leakage current is greater than 10 uA | Replace the insulation rod |
| Transmitter power | Unscrew the cap, dial up the transmitter switch to open position. | Buzzer rang 2 seconds, the indicator light flashing in 1 and 2. | The buzzer rang, or example, said the battery is low. |
The transmitter switch, connect a charger.
After full charge indicator for the green light.
|
| The emitter function | Use the special test line of mains connection (see figure 1), the mains. The receiving host boot. | Buzzer rang 2 seconds, the indicator light flashing in 1 and 2. The receiving host display corresponding to the frequency of the transmitter. | In power under normal conditions, the light is not flashing, host according to the corresponding frequency of 0 . | Transmitter failure, returned to the factory maintenance. |
| The host battery | The host boot | The battery capacity is greater than 1 | Shows the battery is too low, the host automatically power off. | After connect charger, full of for the green light . |
| The host wireless communications | Host machine, emitter accept electric work normally. | The host shows the frequency of the corresponding normal information. | Host shows the frequency of the corresponding to zero. | Return to factory maintenance. |
