Methods for discovering, partitioning, organizing, and administering communication devices in a transformer area network
First Claim
1. A method for forming a Transformer Area Network comprising the steps of:
- executing a discovery procedure comprising broadcasting, by a first Remote Hub on a low-voltage side of a service transformer, a first pilot signal to a first plurality of Remotes, the first pilot signal having a frequency above a low-pass threshold of the service transformer, the first pilot signal beginning on a zero crossing of a first phase on which the first Remote Hub resides;
receiving, at the first Remote Hub, positive responses from a first subset of the first plurality of Remotes confirming the first subset resides on the first phase on the low-voltage side of the service transformer; and
forming, by the first Remote Hub, at least one Transformer Area Network based on the first subset of the first plurality of Remotes thereby excluding any Remotes not powered by the service transformer.

Abstract
A system and methods for managing a transformer area in an electrical distribution grid having at least one substation transformer and one service transformer are presented. At least one Remote Hub governed by a policy may be provided, which collects data about the transformer area. The Remote Hub may also execute a discovery procedure to inventory Remotes in the transformer area. The Remote Hub may use the collected data to detect events, such as exceptional conditions, configuration changes, or derived results, within the transformer area. Based on the collected data, the Remote Hub is able to transmit data about the transformer area via a Substation-to-Edge channel. A method and system for forming and establishing boundaries of Transformer Area Networks is also presented. Discovery procedures may be used to form Transformer Area Networks out of Remote Hubs and Remotes powered by the same phase of the service transformer.
