Claim Text:
1. A system for monitoring power, comprising: a polyphase distribution transformer monitoring (PDTM) device configured to interface with electrical conductors electrically connected to a transformer, the PDTM device further configured to measure a current and a voltage in each of the electrical conductors simultaneously, the PDTM device comprises a plurality of free-moving satellite current sensors, each current sensor undetached from the other current sensors, each satellite current sensor is separately and electrically coupled via a current cable to one of a plurality of connectors on a control box for which to deliver data indicative of current sensed by the current sensors and each current cable is paired with one of a plurality of voltage cables and each current cable and voltage cable pair is coupled to the same connector; and a processor configured to calculate values indicative of power corresponding to the transformer based upon the currents and the voltages measured and transmit data indicative of the calculated values, the processor further configured to determine a time associated with each current and voltage measured.
