Kind Sirs:
I have symmetrically connected three 35 ufd motor run caps between three 480 volt phase lines. While monitoring the phase-neutral voltages in an ON/OFF test, data shows that, with the caps in the circuit, the three WYE voltage magnitudes are closer to the mean value. 274, 277, 280 become 276, 277, 278 with caps.
How do the caps charge and discharge between the AC phases to achieve this result. Please suggest a mechanism for this process (quantitative, if possible) and provide references for further study.
Thanks, RTE
