How can a transformer have negative voltage regulation?
A few texts state that a leading power factor can give rise to negative power factor, but I have not been able to figure out how this is possible.
One vague explanation in my mind is that capacitance across the secondary terminal will somehow cancel out the leakage reactance on the primary side, thus resulting in a higher primary voltage and hence higher secondary voltage as well.
Can somebody please describe more accurately.
