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 accurately 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. The wiring is simple, testing and recording are convenient, greatly improving 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, easy and quick to use, making it the preferred product for power users at all levels.

 

　　I. Functional Features

 

　　1. Can measure 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. Operators only need to input the correction index based on 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, ensuring accuracy without switching gears. It will not damage the instrument due to incorrect 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 test data at any time through the micro printer.

 

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