Automatic Current Transformer Turn Ratio Tester /ttr meter

 Introduction

Measure the voltage ratio of three or single phase transformer.

All the data and test results are shown on a 320*240 LCD screen.

All the test results could be printed by the micro printer or saved in the storage of the tester.

Good performance on auto protection and anti-disturb.


 Main functions

1. The voltage ratio measurement of three or singe phase transformer

2. The group vector measurement of three phase transformer.

3. The polarity measurement of single phase transformer or CT/PT

4. Voltage ratio error calculation

5. Voltage ratio range calculation of three phase transformer

6. Current transformer ratio measurement

7. Excitation current measurement in ratio testing

8. Reproduction the AC test voltage from power source to reduce the effects of bad power source

9. Save the test results in the memory internal the tester

10. Print the test results by micro printer

11. Reverse connection detect unit to prevent the high voltage injected to the operate

12. Over current protection in test voltage

13. Upload the test results to make word report by RS232 interface
