The transformer ratio tester is a new generation of intelligent transformer ratio tester, which is based on single chip microcomputer for measurement calculation and automatic control. The Chinese menu operation interface has the advantages of intuitive display, good stability, high accuracy, wide measurement range and no three-phase power supply on site.
Balance transformer ratio tester
The technical features of the balance transformer ratio tester are as follows:
1. A three-phase or single-phase standard power supply with stable amplitude and constant phase is integrated in the instrument.
2. Testing single-phase or three-phase transformer is not only suitable for general power transformer, but also especially suitable for 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, Zui has a large output of 5A, which is especially suitable for low-voltage transformer test, and the turn number test of semi-finished products in the manufacturing process of CT and Pt.
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 instrument adopts no local discharge and voltage regulation output, and the speed of voltage regulation and measurement is fast. 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, and the instrument automatically judges the rated transformation ratio of the current tap: in the process of multi tap voltage test, only one parameter needs to be set, and the instrument automatically judges the current tap, greatly improving the working efficiency.
8. The instrument 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. Panel type thermal printer can print test results on site quickly.
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.
The above is the technical characteristics of the balance transformer ratio tester. If you don't understand anything about this product, you are welcome to consult our online customer service for details~
