1. A voltage harvesting device for use in a power distribution system, the voltage harvesting device comprising:
a transformation circuit comprising,
at least one first impedance component,
at least one second impedance component comprising,
a first input for coupling to a loaded or unloaded source line voltage,
a second input for coupling to the at least one first impedance component, and
an output for coupling to a load,
wherein an AC voltage on the output of the second impedance component is a higher voltage than the loaded or unloaded source line voltage; and
a voltage converter for converting the AC voltage on the output of the second impedance component to a DC voltage usable by at least one distribution system communication and control device operatively associated with the voltage harvesting device.
