Abstract
Extensions to the concept of using a power line carrier to convey a data record from the secondary side of a first transformer to a receiver in a power distribution substation include receiving the data record over a secondary data path in the event that the primary path is not available. The data record received over the secondary path through a second transformer rather than the first transformer must not interfere with other data transmissions from other transmitters and needs to identify the source of the transmission. An alternative to using a secondary data path through second transformer rather than the first transformer is to provide a data bridge around an opening in the primary path. This abstract is drafted to aid those searching for relevant patents and does not represent a legal limit on the scope of claims arising from patents claiming priority to this application.
