Description
Overview
GAOTek TTR tester is process of user handover and maintenance test that the transformer test must be done, so it can be used for quality supervision of transformer, to prevent the transformer inter-turn short circuit, open circuit, connection error, voltage regulating switch internal fault or contact failure. We develop the production of automatic ratio testers according to the user’s requirements on-site use, make the operation more convenient, complete functions, reliable data, test speed is greatly improved. To meet the needs of all kinds of small medium and large transformer test.
Features
- Easy to operate
- The measurement range of ratio:1-9999.9
- Powerful: both single phase
- measurement can be achieved
- but also, to achieve the automatic test
- three phase windings
- the connection group can be arbitrarily
- selected, once the completion of the measurement
- AB, BC, CA three-phase variable ratio, error
- line group parameters
- Fast measuring speed
- Once the measurement is completed
- automatic cut off the test power
- Set data, automatic measurement results
- can view the previous data
- Test transformer on load
- only need once input ratio
- Easy to carry
- suitable for field operations
