Power path identification in a power distribution system

A path identification device for power path identification, the device configured to be provided at a connection point in a power distribution system comprising:

• a data over power communication module for data signal transmission in a power line at the connection point using a predefined frequency and for data signal reading from the power line at the connection point;
• a path identifier adding component for providing an identifier value to the data over power communication module for transmission at the connection point;
• and
• a path identifier reading component for receiving a read data signal from the data over power communication module of a path identifier at the connection point of an infrastructure, wherein the path identifier is formed of concatenated identifier values of multiple connection points on a path of the power line to or from the connection point.

A system for power path identification in a power distribution system, the system comprising:

• a plurality of path identification devices each provided at a connection point of the power distribution system and configured to:
• transmit a data signal through a power line infrastructure including adding an identifier value of the connection point to the data signal to form a concatenated path identifier with identifier values of other connection points;
• and
• read the path identifier at the connection point of the infrastructure to obtain power path information to or from the connection point in the power line infrastructure.
