Functional Features
1. Three voltage and six current vectors displayed on the same screen, domestic first; for testing differential protection devices, only one wiring is needed to complete the drawing of the six-phase diagram, greatly improving work efficiency; in cases of small space and difficult wiring, the dual-clamp method can be used for multiple measurements to ultimately draw a complete six-phase diagram.
2. Uses clamp-type current transformers for connection, no need to disconnect the current circuit, safe and convenient.
3. Can perform vector analysis of complex protection devices, determine whether the wiring is correct, and provide correct wiring diagrams for comparison.
4. Can perform conventional electrical parameter tests, simultaneously displaying three-phase voltage, three-phase current, three-phase active power, three-phase apparent power, and three-phase phase angle; and can directly read the voltage amplitude, current amplitude, and power values converted to the primary side of the transformer.
5. Can check for incorrect wiring in three-phase three-wire high-voltage metering devices, analyze and judge 48 types of three-phase three-wire wiring, and directly provide analysis results; detect malicious changes in metering wiring to prevent electricity theft, effectively avoiding loss of electricity charges.
6. Can perform harmonic analysis of the measured signal on-site, analyze the content of each harmonic from 2nd to 32nd, and automatically calculate the total harmonic distortion.
7. Large screen, high-brightness color LCD display, full Chinese graphical menu and operation prompts for friendly human-machine interaction, touch silicone buttons for more comfortable operation and better feel, wide-temperature LCD with brightness adjustment, adaptable to winter and summer seasons.
8. Large-capacity lithium battery power supply, continuous operation for up to 6 hours.
9. Users can save test data in the form of records at any time for centralized management, filing, and reference, with storage capacity for more than 2000 sets of data.
10. Can upload saved records to a backend management computer for comprehensive analysis and evaluation.
11. Equipped with perpetual calendar and clock functions, displaying the date and time of the test in real-time.
12. Small size and light weight, convenient for on-site use.
13. Reserved USB interface, can be used to replace USB flash drives and other mobile storage devices.
