Profile:
1. Phase meter function - verify the correctness of main variable differential protection and busbar differential;
2, electrical parameter tester function - test the parameters of the power system;
3, metering wire detector function - to detect three-phase three-wire power metering wire inspection;
4, harmonic content test function - field test voltage and current harmonic content;
5, oscilloscope function - display bar chart, as a simple oscilloscope, used to observe the test signal waveform.
Features:
1, three voltage, six current vector on the same screen display; For the test of differential protection device, only one connection can complete the drawing of hexagonal diagram, which greatly improves the work efficiency; When the space is small and the wiring is difficult, the double-clamp method can also be used for multiple measurements and finally draw a complete hexagonal diagram.
2, the use of clamp current transformer connection, no need to disconnect the current circuit, safe and convenient.
3, can carry out vector analysis of complex protection devices, judge whether the wiring is correct, and give the correct wiring diagram for comparison.
4, conventional electrical parameters can be tested, while displaying three-phase voltage, three-phase current, three-phase active power, three-phase apparent power, three-phase phase Angle; The voltage amplitude, current amplitude and power value of the primary side of the transformer can be directly read and converted.
5, can carry out three-phase three-wire high-voltage metering device error wiring check, can analyze and judge the three-phase three-wire 48 kinds of wiring, directly give the analysis results; Investigate and punish the means of stealing electricity by maliciously changing the metering connection to effectively avoid the loss of electricity charges.
6, can carry out harmonic analysis of the measured signal on the spot, can analyze the content of 2-32 harmonics, and automatically calculate the total harmonic distortion degree.
7, large screen, high brightness color LCD display, Chinese graphic menu and operation prompts to achieve friendly human-machine dialogue, touch the silicone button to make the operation more comfortable, feel better, wide temperature LCD with brightness adjustment, can adapt to winter and summer seasons.
8, large capacity lithium battery power supply, continuous work up to 6 hours.
