Abstract
A device for providing power factor correction of a low voltage subnet that includes a low voltage feeder line that is connected to one or more low voltage power supply lines that supply power to one or more customer premises is provided. In one embodiment, the device includes a power factor measurement module configured to measure power parameters for determining a power factor of the power traversing the low voltage subnet; a power factor correction assembly configured to vary a capacitance connected to the low voltage feeder of the low voltage subnet; a controller in communication with the power factor measurement assembly and the power factor correction assembly. The controller may be configured to cause the power factor correction assembly to change the capacitance based on the determined power factor. The controller may form part of a power line communication device configured to provide communications to the one or more customer premises.
