transformer turns ratio meter ttr digital transformer turns ratio meter

I. Feature

1. It can automatically measure the transformer ratio of three-phase and single-phase, and calculate the ratio error.  

2. The number and polarity of transformer connection group can be measured.  And display a secondary wiring vector diagram, intuitive, the instrument has self-calibration function, according to the results of self-calibration can distinguish test line or instrument failure.  

3. Can display transformer voltage waveform diagram and phase relationship of the first and second, can measure transformer voltage harmonics harmonics, convenient analysis of transformer fault.  

4. CT, PT ratio, polarity test function.  

5. Perfect and reliable automatic protection function to ensure the instrument intact in all kinds of abnormal conditions.  

6. The instrument has 128M built-in memory (extensible 4G memory card), which can store all the measurement results. The database can be exported by usb disk, and the database can be opened by Excel spreadsheet.  

7. 7 inch true color touch screen operation, emWinGUI interface, simple and convenient operation.
