In regards to the Active Harmonic Filter. How would one size the filter with both linear and non-linear loads on the bus.

Example: With several non-linear loads with a full load amp rating of 225 Amps @ 480 Volts/60 hz and linear loads of 75 amps. Assuming 35% THD and wanting to be at <5% THD. What would be the proper calculation to find the corrective amps needed for an active harmonic filter.
Regards,
Johnny
