Product Introduction
XHBB128B Transformer Turns Ratio Tester
During the processing of the semi-finished products and the finished products in transformer production, the transformer newly installation before using, or according to IEC and national standard, the turns ratio or voltage ratio should be tested in the circle rate. Traditional bridge method is complicated, and can't read the data directly, and you have to make conversion, the testing results are data of one phase. Turns ratio tester of XHBB128B-type overcomes the shortcomings of traditional bridge method. The monitor adopts big screen with lattice liquid crystal, which has the function of indicating by menu, operating easily and directly. It finishes test of three-phase voltage ratio or turns ratio once, fast testing and high precise.
Functions and Characters:
1Test rating widely, maximum is 6000or 10000
2.High-test speed, it can finish three-phase test about 13 seconds.
3.Test vector group characteristic.
4.Protective function when the high and low voltage side made upside down.
5.Protective function when the short circuit of the transformer and the short circuit between turns.
6.Print output.
7.Small volume, lightweight.
