JSBC-901 Series Fully Automatic Transformer Turn Ratio Tester TTR Test Set

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 (CT that knee-point voltage should be more than 80V).

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 operator.

12. Over current protection unit integrated in software and hardware.

13. Upload the test results to PC by RS232 and make word report by software.
