Portable Multifunctional Transformer Turns Ratio Group Tester RSBC-V

Product Specification

Portable Multifunctional Transformer Turns Ratio Group Tester RSBC-V

1. The instrument is equipped with lithium battery, which can be used for ratio variation test on site without external power supply. A single charge can satisfy at least 100 transformer tests;
2. The instrument is integrated with single-phase and three-phase standard power supply with stable amplitude and constant phase.
3. The output power of the internal standard power supply is large, with a maximum output of 5A, which is especially suitable for low-voltage transformer testing, as well as semi-finished products in CT and PT manufacturing process.
4. Accurately and quickly test the turn ratio, turn ratio error and phase difference of the current transformer (CT) and voltage transformer (PT).
5, the test of single-phase or three-phase transformer, suitable for z-type winding transformer, rectifying transformer and railway electrical system of Scott, inverse Scott, balance transformer test.
6. High test accuracy. The instrument adopts 16-bit high-precision AD and high-speed DSP processor, effectively ensuring the measurement accuracy and anti-interference ability.
7. The instrument adopts non-local voltage release and regulation output, and the voltage regulation and measurement speed is fast. It only takes 5 seconds to complete the pressure boost and test;
8. The instrument automatically determines the rated transformer ratio of current tap: in the test of multi-tap transformer, the test can be conducted by inputting the voltage regulation ratio of tap switch only once without inputting the current tap number, which greatly improves the work efficiency.
9. It has the functions of overcurrent protection and check wiring.
10, 320x240 large screen, high brightness LCD display, full Chinese menu and operation tips to achieve friendly man-machine dialogue, rotation of the mouse to make the operation easier.
11. It has a real-time electronic clock to automatically record the date and time of the experiment, which is conducive to the preservation and management of the experiment results.
12. Panel type thermal printer, which can quickly print test results on site.
13, the data has power off storage and browsing function, can store 1000 sets of experimental results, and can transfer data with the computer online.
