ZB-II Transformer Ratio Tester

ZB-II Transformer Ratio Tester

1. The full three-phase sine inverter power supply outputs with automatic voltage regulation and soft start and soft stop functions, resulting in fast testing speed and high accuracy.

2. Three phase transformer, single-phase transformer, PT, Z-type transformer ratio, group, polarity testing function.

3. It has blind testing function, which means conducting ratio and group tests without knowing the high and low voltage connection methods.

4. CT variable ratio polarity testing function.

5. It has the function of angle difference testing during single-phase testing.

6. The tap gear can be tested up to 197 gears.

7. The testing range is wide, up to 10000.

8. High and low voltage reverse connection protection function.

9. Output short-circuit protection function.

10. Clock and date display without power failure; The data storage methods are divided into local storage and USB storage. Local storage can store 500 pieces of test data, and local storage can be converted to USB storage; The USB flash drive stores data in Word format, which can be directly edited and printed on a computer.

11. Thermal printer printing function, fast and silent.

12. Small size, light weight, easy to carry and use.
