Functional Features
1. Three voltage channels and six current vector channels displayed on the same screen; The testing of differential protection devices only requires one wiring to complete the drawing of the hexagonal diagram, which improves work efficiency; In situations where space is small and wiring is difficult, the double clamp method can be used for multiple measurements to ultimately draw a complete hexagonal diagram.
2. Using clamp type current transformers for wiring, there is no need to disconnect the current circuit, which is safe and convenient.
3. Vector analysis of complex protective devices can be performed to determine if the wiring is correct, and a correct wiring diagram can be provided for comparison.
4. It can perform routine electrical parameter testing and display three-phase voltage, three-phase current, three-phase active power, three-phase apparent power, and three-phase phase angle simultaneously; And it can directly read and convert the voltage amplitude, current amplitude, and power values to the primary side of the transformer.
5. Can perform error wiring inspection for three-phase three wire high-voltage metering devices, analyze and judge 48 types of three-phase three wire wiring, and directly provide analysis results; Investigating and punishing malicious methods of electricity theft that alter metering wiring, effectively avoiding electricity bill losses.
6. It can perform harmonic analysis of the measured signal on site, analyze the content of each order of 2-21 harmonics, and automatically calculate the total harmonic distortion.
7. Large screen, high brightness color LCD display, Chinese character graphical menu and operation prompts for friendly human-machine dialogue, touch silicone buttons for comfortable operation and good hand feel, wide temperature LCD with brightness adjustment, suitable for winter and summer seasons.
8. Powered by a large capacity lithium battery, it can work continuously for up to 8 hours.
9. Users can save the test data in the form of records at any time for centralized and unified management, filing, and reference, and can store more than 200 sets of data.
10. The saved records can be uploaded to the backend management computer for comprehensive analysis and review.
11. Equipped with perpetual calendar and clock functions, it displays the date and time of the testing work in real time.
12. Small size, light weight, easy to use on site.
13. Reserved USB interface, which can be used to replace USB flash drives and other mobile storage devices with instruments.
