Technically speaking, capacitors should be installed between the transformer and the load. The utility company will distinguish the power system as having a unity power factor regardless of where the power factor correction capacitors are situated on the distribution line as long as they are properly sized. This is known as Power Factor Correction.
Since PushECO units are energy generators, the most effective location for installation of these units would be in locations precisely at the motor where energy is to be consumed; where the units will be able to supply the PushECO reactive current component to the load since the PushECO is capable of storing reactive energy in its magnetic field when the unit charges up and releases it when it discharges. The generator or transformer must still be able to supply the load’s KW needs, but the reactive current component is going to be supplied by the PushECO unit instead of the generator provided by the utility company.
Being distinctively different from other electrical capacitors, the PushECO unit performs as more than just a power factor correction alongside its system-side surge protection facilities; the PushECO unit primarily serves as Power Optimization Technology. Peak performance efficiency and economics is better achieved when the PushECO unit is installed as close to the load as possible because doing so allows the total line current to the load to be reduced significantly, also resulting in a reduction of any voltage drops in the line as well as total losses in the line conductor which may come in the form of heat and/or noise. Other electrical capacitors are not able to provide the optimization value that the PushECO unit does.
