Product Details

1. Screen display content: Wireless high-voltage phase detector, different phase, same phase, frequency, X, Y

2. Power: The host uses rechargeable power, and the X and Y collectors use 5 AG10 batteries.

3. Auto power off: The host will automatically power off about 8 minutes after startup.

4. When contacting the measured strong electric field, the instrument will automatically alarm.

On-site phase verification instructions:

① First, hang the X and Y collectors on the same high-voltage line respectively. The host display should show X and Y in the same phase, with a phase difference of 000°┉001°.

② When performing phase verification on high-voltage lines, arrange the X and Y collectors as follows: AA′ same phase 000°┉001°: AB′ different phase 120° or 240°, BB′ same phase 000°┉001°, BC′ different phase 120° or 240°, CC′ same phase 000°┉001°.

③ To obtain the optimal value, keep one collector stationary at a collection point on the high-voltage line, and move the other collector around another collection point on the high-voltage line front, back, left, and right, or swap X and Y to find the best phase angle.

④ During phase verification, if the test data for AA′, AB′, BB′, BC′, and CC′ all show different phases, this is due to different wiring groups of the two tested power supply lines, which may result in a phase difference of 30° or 60°. The following introduces the measurement standard in this case (using a 30° phase difference as an example): The test method is the same as ① and ②, and the results should be: AA′ different phase 30°, AB′ different phase 120° or 240°, BB′ different phase 30°, BC′ different phase 120° or 240°, CC′ different phase 30° (Note: 120° and 240° only indicate positive or negative phase sequence).


⑤ When measuring ≥10KV, X and Y can be directly placed on the conductor or insulation layer for phase verification.


⑥ When performing phase verification at ≥66KV, the X and Y collectors can use contact or non-contact methods. (For example, when measuring 110KV and 220KV, place the X and Y collectors 300mm to 1000mm below the high-voltage wire. When measuring 500KV, place the X and Y collectors 1000mm-2000mm below the high-voltage wire, with a permissible deviation of 300mm left and right.)


⑦ Measuring phase sequence: Assume a certain line is phase A. Place X on phase A and Y on another phase. If it displays 120°, it indicates a positive sequence, and that phase should be "B". If it displays 240°, it indicates a negative sequence, and that phase should be "C".


⑧ Voltage detection: Hang one collector on the high-voltage wire. If the host screen displays the symbol of the corresponding collector, it indicates that the high-voltage wire is live. Conversely, if the host screen does not display the symbol of that collector, it indicates that the high-voltage wire is not live (but the collector cannot replace a voltage detector).
