Measurement of voltage ratio and check of phase displacement

 Measurement of voltage ratios and vector group  (also special PST, extended delta).

TTR measurements check the turns ratio of a transformer for short circuits and magnetising current. By performing a three-phase measurement, the phase shift of any winding configuration can be checked, which can be very useful when measuring transformers with phase shift or rectifiers with unconventional vector groups.
