Transformer no-load loss parameter testerPerformance Characteristics

1. It can measure the no-load current, no-load loss, impedance voltage, load loss, and zero sequence impedance of various types of transformers.

2. It can automatically perform waveform distortion correction, temperature correction (providing two methods of simple temperature correction and additional loss correction), voltage correction (no-load test under non rated voltage), and current correction (short-circuit test under non rated current conditions), which is very suitable for units that do not have slightly larger capacity transformer short-circuit test conditions.

3. It can measure three-phase voltage, three-phase current, average voltage, average current, two-phase active power (due to the use of a two power meter method, only the power of phases A and C is displayed here), and total power.

4. It can measure the content of 2-42nd harmonic of each phase voltage and current, as well as the total distortion rate (harmonic distortion) of each signal.

5. It can display real-time waveforms of voltage and current in each phase, intuitively showing the distortion of the waveform.

6. Voltage circuit width limit: The maximum voltage that can be measured is 750V, and accuracy can be ensured without switching gears. The instrument itself will not be damaged due to incorrect voltage gear selection.

7. The large screen, full Chinese character menu, and operation prompts enable friendly human-machine dialogue. The conductive rubber buttons make operation easier, and the high brightness true color LCD display can adapt to all seasons of winter and summer.

8. Users can print out the results of the test data at any time through a micro printer.

9. All test results can be recorded and saved for future reference.

10. Built in real clock that can display the current date and time in real time, and can also store the test time when storing records.
