Transformer Turns Ratio Tester
Darui Electric recommends:
The Transformer Turns Ratio Tester is a new generation intelligent turns ratio testing instrument that uses a microcontroller as the core for measurement calculation and automatic control. It features a full Chinese menu operation interface, with advantages such as intuitive display, good stability, high accuracy, wide measurement range, and no need for a three-phase power supply on site..
Functional Features
1. Automatically measures the connection group.
2. Automatically performs group transformation, and can directly measure the turns ratio of single-phase and three-phase transformers and mutual inductors.
3. Automatically switches phase sequence.
4. Automatically switches range.
5. Automatically calibrates the meter.
6. After inputting the standard turns ratio, it can automatically calculate the relative error.
7. After one measurement is completed, the test voltage is automatically cut off.
8. Measurement results are automatically saved, test data can be printed, and 20 historical measurement data can be stored.
2. Built-in power supply, automatically generates a three-phase high-power test power supply.
3. Can measure the no-load current, no-load loss, short-circuit voltage, and short-circuit loss of various types of transformers.
4. Can automatically perform 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 result. It is 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 up to 750V, and accuracy can be guaranteed without switching gears. It will not damage the instrument due to wrong 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 to achieve friendly human-machine dialogue. Touch buttons make operation easier, and the wide-temperature LCD with brightness adjustment can adapt to all seasons.
7. Users can print out the test data through the micro printer at any time.
8. Test result storage function, can store 200 sets of capacity test data.
