Get PMI's detailed tips for analyzing and recording transformer K-factor:
Make your measurements in a “normal” steady-state waveform cycle, before or after a waveform transient.
Periodic capture waveforms are preferred for K-factor calculation.
Pay attention to the amount of current (RMS value) that is involved in large K-factor measurements. If the current is low compared to the 60 Hz transformer rating, the K-factor may not be an issue...
