Transformer Loss Parameter Tester is a high-precision instrument specially developed and researched by our company for measuring transformer no-load and load parameters. It can precisely measure a series of parameters such as no-load current, no-load loss, short-circuit loss, and impedance voltage of various transformers.

 

　　The instrument has the advantages of small size, light weight, high measurement accuracy, good stability, and simple and easy operation. It can completely replace the previous method of measuring transformer loss and capacity using multiple meters. With simple wiring and convenient testing and recording, it greatly improves work efficiency. It uses a large-screen graphic liquid crystal display as the display window, with graphic menu operation and Chinese prompts, integrating multiple parameters on one screen. The human-machine interface is friendly, and it is easy and quick to use, making it the preferred product for power users at all levels.

 

　　I. Functional Features

 

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

 

　　2. Can automatically perform temperature correction, voltage correction (no-load test under non-rated voltage), current correction (short-circuit test under non-rated current), and DC resistance correction. The operator only needs to input the correction index according to the transformer type, and the instrument will automatically calculate the corrected results.

 

　　3. Wide voltage measurement range: The maximum voltage measurement is up to 750V, and accuracy can be guaranteed without switching gears. It will not damage the instrument due to incorrect voltage gear selection.

 

　　4. Large screen, full Chinese menu and operation prompts achieve friendly human-machine dialogue. Conductive rubber keys make operation easier, and the high-brightness LCD display adapts to all seasons.

 

　　5. Users can print out the test data at any time through the micro printer.

 

　　6. All test results can be saved in the form of records for future reference.
