Apparatus, system, and method for detecting optical events associated with distribution transformers

Abstract

A distribution transformer system includes a distribution transformer and a distribution transformer monitoring device (DTM). The DTM includes an optical sensor operable to generate an output signal (e.g., an output voltage) in response to incident light, a communication interface, non-transitory memory storing processor-executable instructions, and a processor operably coupled to the optical sensor, the communication interface, and the memory. The processor is operable in accordance with the processor-executable instructions to, among other things, determine whether the output signal generated by the optical sensor substantially corresponds to one of multiple stored data signatures representing light producing events (such as arcing, fire, or the presence of unexpected ambient light) and, when such criterion is met, communicate an alert to a remote computing device via the communication interface. The distribution transformer may be pad-mountable, aerially mountable (e.g., mountable to a utility pole), or cabinet mountable, as applicable.
