Abstract: A transformer monitoring device has one or more voltage sensors and/or one or more current sensors integral with a housing for detecting a voltage of a power cable of a transformer. The transformer monitoring device can be configured to monitor voltage levels, and cause alerts to be issued if voltage levels drop and/or spike beyond operator-established tolerance(s).

Abstract: A transformer monitoring device has one or more voltage sensors and/or one or more current sensors integral with a housing for detecting voltage and/or current of a power cable of a transformer. The transformer monitoring device can be configured to monitor voltage data, current data, voltage imbalance, phase angle, outage detection and restoration detection, and/or transformer temperature changes, etc., and cause alerts to be issued directly and/or by a remote central computing device if voltage levels drop and/or spike beyond operator-established tolerance(s), and/or if transformer temperature changes occur outside of operator-established tolerance(s), and/or if a power outage or power restoration occurs, and/or if voltage imbalance occurs, along with additional alert messaging capabilities to be provided by the transformer monitoring device where utility operator personnel would find value.

Abstract: The present disclosure is a system for reducing greenhouse gas emissions that has an intra-grid sensor coupled to a secondary side of a transformer, and the transformer delivers power to a customer premise through a meter. Further, the intra-grid sensor measures an amount of power at the transformer to be delivered to the customer premise through the meter and transmits data indicative of the measured power at the transformer to a server. Also, the system has a processor resident on the server that ascertains non-technical loss based upon the data indicative of the measured power.
