Abstract
A method to detect a phase connection of a receiver of a power line communication system includes providing a first connection between a transmitter and one phase of a multi-phase power line. A zero crossing of a first signal provided by the first connection is detected. A first timestamp is generated before a packet is transmitted by the transmitter and added to a header of the packet. A second connection is provided between the receiver and one phase of the multi-phase power line. A zero crossing of a second signal provided by the second connection is detected. A second timestamp is generated when the packet is received by the receiver. The value of the first timestamp is compared to the value of the second timestamp to determine whether the one phase of the first connection is the same as the one phase of the second connection.
