Abstract
A system for monitoring an electrical power system includes one or more transducer units, each of which has a current measuring device and a voltage measuring device coupled to a respective one of the phase conductors of the power system, and a transducer wireless communications device. The transducer wireless communications device of each transducer unit transmits the measured current data and voltage data to a base unit. The base unit generates one or more electrical parameters relating to the power system using the received current data and voltage data. Also, a method of monitoring a power system including generating current and voltage data for each phase conductor at a first location, wirelessly transmitting the current and voltage data to a second location, and generating at the second location electrical parameters relating to the power system using the current and voltage data for each phase conductor.
