1. A power line data transceiver for transmitting or receiving data over a power line, the power line being adapted to distribute electric power, the power line comprising a shielded cable, which comprises at least two wires and a conductive shield shielding the at least two wires, and the power line being configured to be coupled to an electric load, the power line data transceiver comprising:
a data transceiver coupled to the at least two wires of the shielded cable via a capacitive coupling network, the data transceiver being configured to transmit or receive a data signal over the at least two wires of the shielded cable; and
a power supply coupled to the shielded cable over an inductive coupling network, wherein the power supply is configured to inject a feeding current on the at least two wires of the shielded cable for feeding the electric load with electric power, and is configured to receive a return current from the electric load over the conductive shield of the shielded cable.
