Handheld intelligent communication acquisition three-phase power multi parameter tester

　　The main purpose of the three-phase power multi parameter tester is to

This instrument is used by the electric energy metering and electricity marketing departments of the power system, and can perform on-site detection of secondary circuits for the following purposes:

1. Automatically distinguish the positive and negative phase sequence of the line;

2. Multi parameter measurement of power lines;

3. Determine the speed of operation of the electricity meter, calculate the correction factor, and collect electricity fees reasonably;

4. Check the transformation ratio and polarity of the low-voltage CT, and whether the nameplate matches the actual object;

5. Discrimination between inductive and capacitive circuits;

6. Can be equipped with a high current clamp meter for power line loss management data collection, real-time collection of unbalanced data recording;

7. Used as a leakage current meter, etc.

　　Main functions and characteristics of three-phase power multi parameter tester

1. The equipment consists of an AC acquisition device and a tablet handheld device. The AC acquisition module collects signals and the tablet handheld device displays them;

2. Measure the phase separation and total power of three-phase voltage, current, frequency, active power, reactive power, apparent power, and power factor online, and display multiple phase relationships of electrical U-U, U-I, and I-I. Provide Chinese prompts for positive and negative phase sequence; Hexagonal vector diagram display;

3. Automatically identify the load characteristics of the power line and check the wiring of the secondary circuit of the power line;

4. Automatically identify the wiring results of the secondary circuit for energy metering (three-phase four wire and three-phase three wire), indicate the incorrect location, display the secondary wiring diagram and power expression, and automatically calculate the correction factor.

5. Dual power supply: The measuring end is directly powered by a high-performance lithium battery, and the instrument can work continuously for 10 hours when powered by the lithium battery.

6. The tablet handheld device is equipped with intelligent APP data collection software, which can collect real-time on-site data and automatically draw curve graphs for data analysis and management. 24-hour real-time data collection and monitoring of on-site electrical equipment, detecting three-phase load imbalance and load fluctuation process monitoring, displaying voltage deviation, three-phase voltage imbalance rate, and three-phase current imbalance rate.

7. Wireless transmission and communication function: Bluetooth wireless+intelligent APP dedicated software enables data collection, storage, viewing, and analysis on Android tablets or handheld terminals. The APP system software has strong applicability, suitable for all Android phones, with a graphical Chinese interface and touch operation.

8. The data storage capacity is large, including voltage, current, phase, power, power factor, vector diagram, secondary circuit wiring diagram and other test data. Equipped with data query management function, it can access stored test data including electrical parameters, vector diagrams, wiring diagrams, etc.

9. The detection data can be uploaded and saved in the cloud space, and the backend scheduling can remotely retrieve the detection data from different locations.

10. The APP application software based on the Android system handheld terminal has more powerful functions. The terminal handheld can be used for investigation and evidence collection functions (such as photography, video recording, positioning, etc.), and on-site evidence collection pictures and geographical location data can be remotely read in cloud space.

11. Software lifetime free remote upgrade, handheld terminal SD card expansion storage, multimedia playback, installation of various applications * *, system functions can be expanded with software upgrade.

12. The communication collection equipment is small in size, light in weight, and has a wrist guard to prevent the operator from accidentally damaging the instrument.
