Nickname: TTR Tester; turns ratio; transformer turns ratio
Feature:
1.Suitable for test turns ratio and phase difference of special transformer.
2.Particularly suitable for measuring rectifier transformer with phase shift, intuitively display angle of phase shift.
3.Automatically generate stable amplitude, phase constant three-phase (120 °) or two phase (90 °) power supply.
4.Not restricted by the internal wiring mode of the transformer, directly measure voltage ratio and phase angle difference of HV and LV side.
5.Simultaneous 3-phase measurement.
6.Disposable set test parameters, test directly after converting tapping switch, automatically determine tap position and standard ratio.
7.Fast speed, test time 8 seconds.
8.Test results are not affected by power-frequency power frequency and amplitude fluctuations.
9.Internal protection function with over-current protection, high and low voltage reverse connection protection.
10.Can completely by the host computer to control the whole testing process, save the data, print the test report.
11.Auto save the test results, up to 99 groups.
