3-Phase Ratiometer
PWR1-3B - Schuetz Messtechnik GmbH (Schuetz Messtechnik GmbH)
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.
