Product Description

TTR-I IEC Standard Fully Automatic Transformer Turns Ratio Meter

Introduction:
1. TTR-I IEC Standard Automatic Transformer Turns Ratio Meter is designed according to IEC76-1 and IEC60044.
2. TTR-I IEC Standard Automatic Transformer Turns Ratio Meter can be applied to test the turns ratio and group vector of single or three phase transformer.
3. The connection group of three phase transformer also can be calculated with the ratio.
4. All parameters can be measured in one test for three phase transformer.

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. Reproduce AC test voltage from power source to reduce 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.
