Patent ID: 8103466

Claim:
A monitoring system configured to determine at least one phase conductor line condition in each of a plurality of segments of a phase conductor line of a distribution system, the monitoring system comprising: a first sensor positioned at a first location along the phase conductor line, wherein the first sensor is configured to generate a first set of synchrophasor data; a second sensor positioned at a second location along the phase conductor line, wherein the second sensor is configured to generate a second set of synchrophasor data; and a processor configured to receive the first set of synchrophasor data and the second set of synchrophasor data and to determine a primary side voltage of at least one distribution transformer electrically connected to the phase conductor based on a secondary side voltage of the at least one distribution transformer, wherein the processor is further configured to determine at least one phase conductor line condition comprising at least power dissipation in each of the plurality of segments based on the first set of synchrophasor data, the second set of synchrophasor data, and the primary side voltage of the at least one distribution transformer.
