Product Description
Three Phase Transformer Turns Ratio Tester


GDB-D Transfomer Turns Ratio TTR Tester is specially designed for three- phase transformer in power system, especially for transformer of type Z winding and other transformers whose zero-load current is relatively high.The tester has wide testing range, fast testing speed, favorable repeatability, flexible data processing, convenient connection, complete protection, easy learning and convenient operation.

1 .Applicable to transformers connected in Z type.

2 .Two output voltages are optional and applicable to transformer whose zero-load current is relatively high.

3. Have wide testing range and the highest transformation ratio may reach 10000.

4 .Automatically calculate tap position.

5. Fast speed, which is only 18 seconds for three-phase

6. Favorable repeatability.

7 .Automatically save 99 data at most.

8 .Flexible data processing, including retrieval, print, transfer to U-disk, delete and upload to PC computer for testing.

9. Have transformer short-circuit protection and interturn short-circuit protection functions. In case of short circuit, relevant 

information will be displayed on the LCD screen in characters.

10. The upper computer could control the whole testing process, save data .

11. Struction manual is attached to the tester, providing convenience for users.

12 .The tester is small and is a little bigger than a piece of A4 paper.

13. The tester is light and its weight is only 6.9kg.
