Identification of electrical grid phase information for end-points in a grid network
First Claim
1. A method, comprising:
- requesting a phase-related response from an end-point that does not know its phase in a polyphase power source system;
receiving the phase-related response from the end-point, the phase-related response configured to relay an identification of the end-point and related phase information without indicating an actual phase of the end-point;
correlating the phase information of the phase-related response to a known phase of a known-phase device; and
identifying the actual phase of the end-point based on the correlation, whereinthe phase-related response is a message transmitted on a particular power-line of the polyphase power source system, the related phase information of the phase-related response being the fact that the message was transmitted on the particular power-line.

Abstract
In one embodiment, a requesting device (e.g., head-end application) requests a phase-related response from an end-point that does not know its phase in a polyphase power source system. In response, the requesting device receives the phase-related response from the end-point, where the response relays an identification of the end-point and related phase information without indicating an actual phase of the end-point, e.g., on which power-line is a response generated or at which time is a zero-crossing of the power source'"'"'s waveform. The phase information of the phase-related response may then be correlated to a known phase of a known-phase device, such that the actual phase of the end-point may be identified based on the correlation.
