Transformer Turn Ratio Tester

1. Main functions and characters

 1 Measure three phase transformer connection group according to IEC76

 2 Identification group of transformer according to IEC76

3 Measure the ratio of three phase transformer according to IEC76

4 Indicate polarity of single transformer according to IEC60044

5 Measure the turn ratio of PT and CT according to IEC60044

6 Switch measurement range

7 Measure the excitation current injected to transformer coil

 8 Calculate the ratio error according to presetting standard ratio

 9 Testing voltages is cut off automatically when one test is finished

10 Calculate standard ratio according to regulate rate in load transformer testing

11 Protection automatically when primary and secondary coil is in reverse connection

12 Protection automatically power output circuit overload

13 Test sine generated by tester has low distortion and the quality of test voltage does not affected by system voltage.
