Abstract
A system of sensors associated with a branched conductor of an AC power line using the conductor as the communication medium between different sensors. The communication is carried out at frequencies higher than the powerline frequency. At least one sensor is provided in every branch in the vicinity of every branching point of the conductor. Synchronous measurements are carried out of the root mean square current passing through every branch of the conductor and the direction of energy flow in the branch. Results of the measurements are regularly reported throughout the system. An arrangement is provided for analyzing the results of the measurements to determine the graph topology of the branched conductor and ascertain the distribution of the root mean square current passing through every branch of the graph.
