Two-way station identification instrument test method and identification instrument interpretation

1. Two-way station user identification instrument high-power FSK power load transmission communication mode, the theoretical communication distance meets any power supply range of the station area.
2. Special pulse current emission and detection methods ensure that there will be no string signal errors due to the adjacent high voltage.
3. Fast and convenient identification function of the station area, the extension is initiated, the test time is less than 6 seconds, and the result accuracy is 100%; the result description is simple, clear and clear, and the display content includes the transformer station number where the tested user is located. And the phase of the meter to be tested (A phase, B phase, C phase), the display results are intuitive.
4. The branch identification function accurately determines the branch of the power supply line of the station where the user is located. A single host can detect 3 branches at the same time. Multiple hosts can work simultaneously to expand to 18 branches.
5. It has the function of mutual transformer mutual test, and multiple hosts work at the same time, which can accurately determine the independence of each tested change station and whether there is electrical connection.
6. The two-way station user identification instrument has zero-fire line discrimination function, which can display whether the zero-fire line wiring is correct and whether there is reverse connection.
7. With phase sequence discrimination function, it can be judged whether the phase sequence of each phase of ABC is "positive phase sequence" or "reverse phase sequence".
8. Two-way station user identification instrument current detection using 50A clamp meter, 100A clamp meter, 250A clamp meter and 500A clamp meter (optional flexible clamp).
9. A variety of working modes are arbitrarily selected, convenient to combine, flexible to set up; with independent power carrier, independent current pulse transmission and power carrier and current pulse integrated mode and other communication methods.
10. Multi-machine working mode, the instrument can be set as the host or extension, and each device can be set as the host or extension; support one main multi-point, multi-master one-point, multi-master multi-point three modes, convenient for users to use, can effectively improve the work effectiveness.
11. Accurately measure three-phase voltage, current, active power, phase angle, power factor, frequency, total power and other electrical parameters, which can be used as electric parameter tester.
12. The two-way zone identifier can display the phase loss of the voltage and automatically give a prompt on the LCD screen.
13. Power quality analysis of low voltage grids. The instrument can accurately measure the three-phase voltage 2-31 harmonics and the three-phase current 2-31 harmonics, and also measure the total harmonic distortion of each phase voltage and current.
14. Vector display function. The instrument can display the vector relationship diagram of the three-phase voltage and the three-phase current, which is convenient for checking the wrong wiring of the low-voltage user metering device.
15. Simple oscilloscope function. The instrument can display the actual waveform of the three-phase voltage and three-phase current, and the user can see the waveform of the user under test at a glance.
16. The instrument has a self-test function. When the damage occurs to the device due to overvoltage, shock, etc., the instrument should diagnose the fault and correctly prompt it.
17. The large-screen true color full-transparent LCD screen is still clear under the sun. Chinese and graphical display, friendly interface, intuitive display and easy operation.
18. Conductive silicone button operation mode, reasonable design, easy operation, long life, high sensitivity, avoiding the touch screen mode is prone to failure after a period of use, resulting in inoperability, or poor operational sensitivity and affect the normal use of the user.
19. The two-way zone identifier can save the test results of the zone attribution test in the form of records, including: test date, test time, station change number, meter number, and belonging.
20. The test record can be copied to the background management computer through a mobile storage device such as a USB flash drive for centralized management, and the data records can be classified and statisticed, so that the marketing department can truly grasp the information of the affiliation, the affiliation, and the branch affiliation of each household. Correctly calculate the load distribution, line loss rate and other information.
21. In order to ensure the safety of the operation, the instrument has multiple protections. The power circuit has separate and quick-changeable protection components. In the application of the device, when the line voltage is mistakenly connected during wiring, the two-way zone identifier ensures that there is no damage and prompts the miswired condition, and the instrument cannot perform the test operation.
