Features
1. Automatically measures the wiring group.
2. Automatically performs group transformation, enabling direct measurement of the transformation ratio of single-phase and three-phase transformers and instrument transformers.
3. Automatically switches phase sequence.
4. Automatically switches range.
5. Automatically calibrates the meter.
6. After inputting the standard transformation ratio, it can automatically calculate the relative error.
7. Once the measurement is completed, the test voltage is automatically cut off.
8. The measurement results are automatically saved, test data can be printed, and up to 20 historical measurement data sets can be stored.
Features
1. Can accurately measure the capacity of various distribution transformers, with passive measurement, convenient and accurate.
2. Built-in power supply, automatically generates a three-phase high-power test power source.
3. Can measure the no-load current, no-load loss, short-circuit voltage, and short-circuit loss of various types of transformers.
4. Automatically performs waveform distortion correction, temperature correction, voltage correction, and current correction (short-circuit test under non-rated current conditions). The operator only needs to input the correction index according to the transformer type, and the instrument can automatically calculate the corrected results, making it very suitable for units that do not have conditions for short-circuit tests on slightly larger capacity transformers.
5. Wide voltage range: the maximum measurable voltage is 750V, and accuracy is guaranteed without switching gears. It will not damage the instrument due to incorrect voltage gear selection.
6. Battery remaining percentage indication function, not just a simple low battery alarm.
6. Large screen, high brightness LCD display, full Chinese menu and operation prompts for friendly human-machine interaction, touch buttons for easier operation, wide temperature LCD with brightness adjustment, adaptable to winter and summer seasons.
7. Users can print out the test data at any time through the micro printer.
8. Test result storage function, can store 200 sets of capacity test data.
