It is to test voltage ratio, vector, polarity, ratio error of current transformer and voltage transformer.
Transformer turns ratio meter functions:
| 1 | The voltage ratio measurement for three or singe phase transformer |
| 2 | The group vector measurement for three phase transformer. |
| 3 | The polarity measurement for single phase transformer or CT/PT |
| 4 | Voltage ratio error calculation |
| 5 | Current transformer ratio measurement |
| 6 | Excitation current measurement in ratio testing |
| 7 | Reproduction the AC test voltage from power source to reduce the effects of bad power source |
| 8 | Save the test results in the memory internal the tester |
| 9 | Print the test results by micro printer |
| 10 | Reverse connection detect unit to prevent the high voltage injected to operator |
| 11 | Over current protection unit integrated in software and hardware |
| 12 | Upload the test results to PC by RS232 and make word report by software |
