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). The transformer monitoring device further has one or more environmental sensors including a smoke sensor, ambient temperature sensor, external transformer temperature sensor, a fire/wildfire sensor, a humidity sensor, a noxious gases sensor, a seismic or vibration sensor, and/or a surface and/or ground temperature sensor configured to detect smoke, and/or temperature change indicators, and/or other environmental changes in an area surrounding the transformer, and a processor configured to monitor the smoke sensor, temperature sensors, and/or other environmental change sensors, the processor configured to transmit an alert if smoke, temperature and/or other environmental conditions are detected surrounding the transformer.
