Multifunction Transformer TTR Tester particularly suitable for Z- winding transformers, rectifier transformers and electrical systems railway Scott, inverse Scott balanced transformer. This tester using a large -screen LCD display, friendly man-machine interface, fully functional , easy to operate, it is the ideal instrument for power system , transformer manufacturers and railway electrical systems transformer ratio , group do not , polarity, and the angle of the testing.
Multifunction Transformer TTR Tester Product Features
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
9. Internal protection function with over-current protection, high and low voltage
reverse connection protection.
