Abstract: Determining the number of loads associated with each phase in a three-phase electric power system. The loads can be associated with the consumption of electric power at a node, such as a metering device located at a facility. In one implementation, a central device that is connected to such nodes via a smart grid and a radio frequency mesh network can be leveraged to determine a phase in real time. For example, the central device can include a processor that executes one or more computer program modules which can cause a load tap changer having access to a distribution feeder in the smart grid to vary a voltage level supplied across each phase of the power system. Additionally, the central device can communicate with nodes in the mesh network to cause the nodes to perform voltage measurements and collect information related to such measurements.
