The functional characteristics of the automatic ratio tester

The automatic transformer ratio tester can be used for three-phase transformer test of power system, especially for Z-winding transformer, rectifier transformer and balance transformer test. It is an ideal instrument for transformer ratio, group, polarity and angle test of power system, transformer manufacturer and railway electrical system.

 

 

In order to better improve the working efficiency of users, Zhizhuo measurement and control has developed zc-203b full-automatic variable ratio tester with the latest technology. Its functional features are as follows:

 

1. The automatic ratio tester is integrated with three-phase or single-phase standard power supply with stable amplitude and constant phase.

 

2. Testing single-phase or three-phase transformer is not only suitable for general power transformer, but also especially suitable for testing Z-winding transformer, rectifier transformer and Scott, inverse Scott and balance transformer of railway electrical system.

 

3. The internal standard power supply has a large output power and a maximum output of 5 A, which is especially suitable for low-voltage transformer test and the turn number test of semi-finished products in CT and Pt manufacturing process.

 

4. The turn ratio, turn ratio error and phase difference of CT and PT are measured accurately and quickly.

 

 

5. The instrument adopts 16 bit high-precision AD converter and CPU with DSP (digital signal processing) chip, which effectively guarantees the measurement accuracy and anti-interference ability.

 

6. The full-automatic transformer ratio tester adopts no local discharge and voltage regulation output, which is fast in voltage regulation and measurement. It only takes 5 seconds to complete the pressure rise and test;

 

7. The measurement speed is fast, the test time of a group of data is a few seconds, the full-automatic transformer ratio tester automatically judges the rated transformer ratio of the current tap: in the process of multi tap transformer voltage test, only one parameter needs to be set, and the instrument automatically judges the current tap, greatly improving the working efficiency.

 

8. The full-function transformation ratio tester automatically switches the measuring range according to the tested object.

 

9. It has the function of over-current protection and wiring inspection.

 

10. 320×240 large screen, high brightness liquid crystal display, all Chinese menu and operation prompt realize friendly man-machine dialogue, touch the key to make the operation easier.

 

11. It has a real-time electronic clock, which can automatically record the date and time of the test, which is conducive to the storage and management of the test results.

 

12. The panel thermal printer can print the test results quickly on site.

 

13. The data has the function of power-off storage and browsing. It can store 1000 groups of experimental results and transmit data online with the computer.

 

 

Zc-203b automatic ratio tester adopts large screen liquid crystal display, full Chinese menu and Chinese character printout, with friendly human-machine interface, perfect functions and convenient operation. It is a new generation of ratio tester, which is at the leading level in China.
