The wireless high-voltage nuclear phase analyzer has functions such as phase detection, phase sequencing, and electrical verification

Wireless high-voltage phase detector is used for phase verification and phase sequence verification of power lines and substations, with functions such as phase verification, phase sequence measurement, and electrical verification. The wireless high-voltage nuclear phase analyzer has strong anti-interference ability, meets the requirements of EMC standards, and is suitable for various electromagnetic field interference scenarios. The phase signal of the measured voltage will be extracted by the collector, processed and directly transmitted. Receive and compare the phase using a nuclear phase analyzer, and qualitatively evaluate the results after nuclear phase analysis. Due to the wireless transmission of this product, it truly achieves safety, reliability, speed, and accuracy, and is suitable for various nuclear phase occasions. The wireless high-voltage nuclear phase meter collector has two types of contact heads that can be replaced with each other as needed. When replacing, rotate the contact head counterclockwise to remove it. When replacing the battery, rotate counterclockwise to remove the collector housing. Open the battery cover again and replace the battery
Note: There is a built-in antenna 350mm long at the upper end of the insulation rod * section, which cannot be subjected to voltage withstand test. The insulation voltage withstand between the built-in antenna and the outer wall of the rod is (15) kV

1. First, hang the X and Y collectors on the same high-voltage line, and the host display screen should show that X and Y are in phase with a phase difference of 355 ° -005 °

2. When checking the phase of the high-voltage line, the X and Y collectors should be arranged separately according to the following methods: AA ′ phase 355 ° -005 °; AB ′ phase 120 ° or 240 °; BB ′ phase 355 ° -005 °; BC ′ phase 120 ° or 240 °; CC ′ phase 355 ° -005 °.
3. To obtain numerical values, one of the collectors should be placed on a collection point on the high-voltage line without moving, and then the other collector should be moved back, forth, left, and right around the other collection point on the high-voltage line, or X and Y should be swapped to find the optimal phase angle.
4. During the nuclear phase, test data such as AA ', AB', BB ', BC', and CC 'all show different phases. This is due to the different wiring groups of the two power supply lines being tested, which may result in a phase difference of 30 ° or 60 °. The following is an introduction to the measurement standards when this situation occurs (taking a 30 ° phase difference as an example): The testing method is the same as ① and ②, and the measured 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, the wireless high-voltage phase analyzer can directly place X and Y on the wire or insulation at the same time for phase verification
6. When the voltage is ≥ 66KV, the X and Y collectors can use contact or non-contact methods for phase detection. When measuring 110KV and 220KV, place the X and Y collectors 300mm to 1000mm below the high-voltage power line. When measuring 500KV, place the X and Y collectors 1000mm-2000mm below the high-voltage power line, with a permissible deviation of 300mm on both sides
7. Wireless high-voltage phase analyzer for phase sequence measurement: Assuming a line is phase A, place X on phase A and Y on another phase. If 120 ° is displayed, it indicates a forward phase sequence, which corresponds to "B". If 240 ° is displayed, it indicates a reverse phase sequence, which corresponds to "C".
8. Electrical verification: Hang one of the collectors on the high-voltage wire. If the symbol of the corresponding collector is displayed on the host screen, it indicates that the high-voltage wire is electrified. On the contrary, if the symbol of the collector is not displayed on the host screen, it indicates that the high-voltage line is not powered (but the collector cannot replace the voltage tester).
