Overview
Hospitality Enviro Tech circuit transformer ratio parameter tester 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 tester according to the user’s requirements on-site using, 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
- English menu prompts, easy to operate
- The measurement range of ratio 1 to 9999.9
- Both single phase measurement can be achieved
- Achieve the automatic test of three-phase windings
- The connection group can be arbitrarily selected
- Measurement of AB, BC, CA three-phase variable ratio, error
- Measurement of 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
