Patent attributes
Use of power line carrier communications which introduces a high frequency analog signal onto a cable used to convey power in a portion of an electric distribution network to send a data communication received at a distant receiver through the use of pick-up coil. Changes in the power level of signals received from a remote power line carrier transmitter may indicate that the pick-up coil receiving the signal is starting to degrade. The aggregation of certain power line carrier conveyed data communications about remote transformers and related equipment may be used to look for problems in this transmitter/receiver communication network. The disclosure includes the aggregation of data communications from one transmitter received at several different power line carrier pick-up coils through the phenomenon of cross talk or through the purposeful provision of data along an alternative communication path.
