NR6700 series automatic transformation ratio group tester
NR6700 series automatic variable ratio group tester, the product has a large-screen Chinese character display, friendly interface, small size, simple operation, light weight, convenient reading, good stability, high accuracy, wide measurement range and automatic degree of measurement process Advanced advantages, can directly measure single-phase, three-phase transformers and transformer ratios, errors and other parameters.
◆ True three-phase test: single-phase power input, three-phase current output is generated internally, the test results have better equivalence, and there will be no group misjudgment and other phenomena;
◆ Reverse connection protection function: When the high and low voltage side test lines are connected reversely, the instrument will automatically detect the internal, immediately stop the output and give an alarm to prevent the high voltage from burning the instrument.
◆ Transformation ratio measurement range: 0-1000 Accuracy: 0.1 level
◆ Transformation ratio measurement range: 1000-2000 Accuracy: 0.2 level
◆ Transformation ratio measurement range: 2000-10000 Accuracy: 0.5 level
