Because it does not help the DG. The reduced current is
reactive only and does not load the engine.
If there is too much capacitance the DG can get a leading
power factor and if this is too great lose control of the
voltage.
In the grid capacitors are used to get the power factor
closer to unity and reduce the current. This means the
power lines can be smaller. If the power factor is leading
it is OK because others will have a lagging power factor to
balance it.

In our factory so many iron pillors are exists for supporting the shed/Hangar. If do more no of earthings at one piller instead of doing more earth pits in many locations and running earth strip around the hanger, I can save the money. Please suggest this method is acceptable as per Is specifications though the Earth resitance of the farthest piller is with in the limits as per IS specifications.
