During concrete the utilization:
1), hardware aspect:
Only need 1 voltage acquisition mouth and a current acquisition mouth.
2), software aspect:
During the beginning surveying work, software prompt is gathered reference voltage earlier, selects premeasuring set of currents number then; As: common line is one group of three-phase current, and main transformer is more than two groups, after selecting to finish; Can the prompting user measure every phase current and affirmation respectively; After the finishing collecting, device is drawn according to test data and is shown the corresponding phase graph of a relation, and can store, analyze, report establishment and the function of uploading to the result
3), effect, advantage
The conventionally test appearance begins need spend 15 ~ 20 minutes to generating final report from measurement, and report by manual analysis, completing is prone to make mistakes; And novel phase test appearance begins to generating final report need spend about 5 minutes from measurement, and report is by installing according to test data; Automatically generate phase diagram; And the judged result correctness, and its mode of connection is simple, only needs a voltage acquisition mouth and a current acquisition mouth.
4), instance
Fig. 3 is three coil transformers, three side current phase graphs of a relation.
Measuring process: a, collection reference voltage; B, gather each side electric current; C, generation phase diagram.
Uab is among the figure: main transformer high-pressure side A and B be top-stitching voltage mutually,
Ubc is: main transformer high-pressure side B and C be top-stitching voltage mutually,
