A monitoring system has a polyphase distribution transformer monitoring (PDTM) device that interfaces with electrical conductors electrically connected to a transformer. The PDTM device measures a current and a voltage in each of the electrical conductors simultaneously. Further, the PDTM device has a plurality of free-moving satellite current sensors coupled to flexible cables, and each current sensor is undetached from the other current sensors. Additionally, each satellite current sensor is electrically coupled via a current cable to at least one connector 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 at least one connector. In addition, the system has a processor that calculates values indicative of power corresponding to the transformer based upon the currents and the voltages measured and transmit data indicative of the calculated values.

Transformer monitoring and data analysis systems and methods

The present disclosure is a system for monitoring power that has a unified polyphase distribution transformer monitoring (PDTM) device that interfaces with at least three electrical conductors electrically connected to a transformer. In addition, the PDTM device measures a current and a voltage of each of the three electrical conductors. Additionally, the system has logic that calculates values indicative of power corresponding to the transformer based upon the currents and the voltages measured and transmit data indicative of the calculated values.
