Applications

This instrument is a multifunctional measuring instrument, which is equivalent to two common test instruments: active transformer capacity and characteristic tester + transformer characteristic parameter tester. It can accurately measure a series of power frequency parameters such as capacity, energy efficiency level, no-load loss, no-load current, load loss, impedance voltage, etc. of various transformers. It also compensates and corrects various indicators to ensure the accuracy of various data.

Features

1. Can measure the rated capacity of various oil-immersed, dry-type distribution transformers and power transformers on site

2. The three-phase inverter solution of DAC+power amplifier automatically generates a three-phase high-power test power supply, and the test data is more accurate

3. Built-in large-capacity lithium polymer battery, the rated capacity of the transformer can be tested without an additional power supply

4. Support "GB20052-2020 Power Transformer Energy Efficiency Limit Value and Energy Efficiency Grade". According to the no-load and load losses in the test results, it can be judged that the energy efficiency codes of oil-immersed and dry-type transformers, including but not limited to "S20, SBH21, S22, SBH25", "SCBH17, SCB18, SCBH19", etc.

5. Combined with external power supply, voltage regulation, voltage and current boosting equipment, the no-load current, no-load loss, impedance voltage, load loss and other characteristic data of various transformers can be measured

6. All voltage, current, active power and other data are calculated in true effective value (T-RMS). According to the need of no-load loss, the average effective value of line voltage (AVG-RMS) is also calculated to ensure that the test data is accurate and not affected by power supply harmonics. 

7. All test results are automatically corrected. You only need to input relevant parameters (such as temperature, no-load correction coefficient, etc.), and the instrument can automatically perform multiple corrections such as waveform deformation correction, temperature correction, non-rated voltage correction, non-rated current correction, etc., to make the test results more accurate.

8. In the transformer characteristic measurement, the maximum voltage range can reach 750V, the maximum current range can reach 100A, and the internal protection circuit is equipped. When measuring, there is no need to switch gears to ensure measurement accuracy, and there is no need to worry about burning the instrument due to wrong gear selection.

9. When testing transformer characteristics, the voltage and current ranges can be expanded very flexibly and easily, simply by connecting external voltage transformers and current transformers, which greatly widens the test range of the instrument.

10. Seven-inch color screen, high-brightness LCD display. 

11. Supports Chinese and English languages; friendly human-computer dialogue interface. 

12. The instrument has a built-in micro thermal printer, and the test results can be printed out through the micro printer.

13. Test result storage function, can store 100 sets of capacity test data. 

14. The instrument has a real-time clock to ensure that each test data is saved and printed with an accurate time stamp.
