Hello NCT
Operating a plant with a leading power factor does not benefit you at all unless there is a special request from the power authority.
As you increase the correction on a lagging load, the line current reduces until the power factor is equal to 1.0 (minimum line current) Further increase in correction will cause a leading power factor going below 1.0 and the current will rise.
As the current from a leading power factor is the same as a lagging power factor, you will still be faced with a power factor penalty or maximum demand charge.
A leading power factor will have no particular affect on the supply other than to increase the current over unity power factor, and to increase the potential of resonance in the supply.
Best regards,
