Advantages
The test power supply is generated by the internal power amplifier of the tester, and the waveform distortion rate is less than 0.5% and is not affected by the quality of power supply.
Automatic voltage regulation, with automatic protection functions such as transformer reverse connection, over-current, etc., to avoid damage to the instrument due to incorrect operation.
GDBC-901 Transformer Turns Ratio TTR Tester can be used for power transformer, CT and PT ratio detection.
Convenient standard transformation ratio setting template, don’t need to manually calculate the standard transformation ratio value.
Print the test results by micro printer. You can also upload the test results to PC by RS232 and make WORD report by software.
GDBC-901 Transformer TTR Tester is very light, the net weight is only 10KG. It’s easy to carry. It’s suitable for field test.
Wiring Connection
1)Three phase transformer test
A,B,C are connected to the HV side terminal A,B,C of transformer and a,b,c are connected to the LV side terminal a,b,c of transformer
2)Single phase transformer and PT test
A,B are connected to HV side terminal of single phase transformer/PT and a,b are connected to LV side terminal of single phase transformer/PT. C and c are connected to nothing.
3)CT test
A,B are connected to secondary of CT and a,b, are connected to primary of CT. C and c are connected to nothing.
