Losses of capacitive power factor

Generally for Inductive loads the current vector will be lagging to the voltage vector .In the case of Capacitive loads the current vector will be leading .

In your case 3 pdb loads seems to be inductive and other 3 pdb loads are capacitive.If the capacitors are pure then the current vector will be 90 degrees leading.But in practice capacitors are not pure there will be some resistive loads.Power will be lost on these resistive loads .This will be minimum only.If you go through the data sheet of the capacitors it will be indicated therein.In case further details are required please furnish complete details.
