KPM TURN Ratio tester

KPM’s Transformer Turns Ratio Meter (KPMTTR3) is used to measure the voltage ratio of 3ph or 1ph phase transformer. All the data and test results are showed on a 320*240 LCD. All the test results can be printed onsite by the micro printer . KPM TTR3 is having an inbuilt memory to save the test results. Advance Noise Reduction circuitry makes it ideal for field conditions.

Features :
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. Reproduce 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 detection unit to prevent high pressure injection operation.
12. Over current protection in test voltage.
13. Upload the test results to make word report by RS232 interface.
