Abstract

A distribution transformer system includes a distribution transformer and a distribution transformer monitoring (DTM) device secured to the transformer. The DTM device includes multiple sensors, a controller, and a communication interface. The sensors are configured to monitor physical properties of the distribution transformer. Each of the sensors outputs respective sensor data representative of at least one monitored physical property of the distribution transformer. The controller is configured to receive the respective sensor data from each sensor to produce received sensor data. The communications interface is in communication with the controller and configured to communicate the received sensor data to a remote system for use in determining operational parameters of the distribution transformer. In one embodiment, the distribution transformer system further includes a surge arrester associated with the distribution transformer and the DTM device includes a surge arrester sensor configured to monitor the surge arrester and output surge arrester sensor data.
