DETERMINING ELECTRIC GRID ENDPOINT PHASE CONNECTIVITY
First Claim
1. A method of determining a service phase of an endpoint device in a power distribution system, the method comprising:
- sending a message to a point in the power distribution system requesting a disturbance on one of a plurality of power distribution phases of a feeder line to customer sites;
receiving a report from each of a plurality of endpoint devices at respective customer sites indicating that the requested disturbance was detected by each of the plurality of endpoint devices; and
based on the received reports, mapping at least one endpoint device that reported the detection of the disturbance to the respective phase on which the disturbance was created, thus identifying which of the plurality of phases the feeder line of the endpoint device is serviced by.

Abstract
The service phase of the electrical connection to a customer endpoint device located within a power distribution system is determined by various techniques. At the feeder level, the system may be programmed to induce disturbances, thereby causing missed zero crossings at the customer endpoint devices. The pattern of these disturbances is a controlled one, designed specifically to avoid causing noticeable disruption even to sensitive devices, but to be unusual enough that it is statistically unlikely to be naturally occurring. The monitoring of the zero crossing information is used to determine the phase of the service line to the customer endpoint devices.
