PWR1-3B Ratiometer 3 - PHASE

PWR1-3B Ratiometer 3 - PHASE

The RATIOMETER PWR1-3B is constructed to measure the transformation ratio, phase error and magnetizing current of power- and
distribution- transformers for all three-phases simultaneously. Voltage and current transformers are single phase, power transformers
normally three-phase. Due to the bad quality on industrial lines (phase jitter and shifting, voltage differences between the three phases)
all measurements normally are done single phase, even on three phase ratiometers. T
