JKBB600AJKBB600B transformer ratio tester

JKBB600A/JKBB600B ratio tester is used for measuring the turns ratio or voltage ratio of power transformers and voltage transformers, and can meet the testing requirements of transformer production, installation, operation, and power preventive testing regulations.
Main functions and features:
1. The variable ratio test has a wide range and can measure up to 10000 values.
2. Fast testing speed, completing three-phase testing in 10 seconds.
3. Suitable for a wide range of transformer types, with Z-shaped connection transformer testing function.
4. It has the function of blind measurement of transformer transformation ratio and group.
5. The protection function is complete, with high and low voltage reverse connection and turn to turn short circuit protection functions.
6. After inputting the rated parameters once, it can automatically measure any gear variation value, error value, and tap position.
7. The printer outputs measurement results, with a Chinese menu display and a large color LCD screen.
8. A transformer with 99 tap positions can be measured.
9. It has data storage function and can save data for a long time.
