LOCATION OF REQUIRED CAPACITORS

METHOD #3: AUTOMATIC CAPACITOR BANK
Install an automatically controlled capacitor bank (Autocapacibank™ brand capacitor) that will closely maintain a pre-selected value of power factor. This is accomplished by having a controller switch steps of kVAR on, or off, as needed. This type of bank eliminates the concern of having too much kVAR energized at light load periods.

This method would seem to have much appeal, but it also has a real disadvantage. Since it is usually located near the incoming service entrance switchboard, we find that like the fixed bank this automatic bank does nothing to reduce the conductor losses (and this billed KW-Hrs). Remember that the reduction in conductor losses using Calmount^® brand capacitor can be sizeable.
