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 |
