China Automatic Transformer Turns Ratio Tester

GDB-D Transformer turn ratio teseter is designed for three phases transformer in power system and especially for Z type winding transformer and other transformers with relatively large no-load current. The instrument is with wide range, fast testing speed, favorable respeatability, flexible date processing, convinent connection, perfect protection, easy learning and convinent operation.
Features
1. Applicable to Z type winding transforer.
2. Two output voltage can be optional and able to test transformers with relatively large no-load current.
3. With wide range, the highest turn ratio may reach 10000.
4. Automatically calculate the tap position.
5. Fast testing speed which is only 18s for three phases
6. Favorable repeatablity.
7. Automatically record 99 data at most.
8. Flexible data processing which can search, print, transfer to U disk, delete and upload PC for testing.
9. Having the protection fuction of transforer short circuit and turn-to-turn short circuit. The corresponding word will be displayed on the LED once there is short circuit.
10. Computer can completely controls the whole process, record data and print test report.
11. Built-in manual that can be consult occasionally.
12. With small size and light weight.
