Abstract
A system, device, and method of providing information for a power distribution system is provided. In one embodiment, a method of using a device that receives power from the low voltage power of the power distribution system and experiences a power loss during a local power outage may perform the processes of monitoring a voltage of the low voltage power line, detecting a voltage reduction below a threshold voltage for a predetermined time period, storing information of the voltage reduction in a non-volatile memory prior to the power outage, and transmitting a notification to a remote computer system prior to the outage. The monitoring may comprise making a plurality of measurements of the voltage during a time interval and averaging the plurality of voltage measurements. In addition, the method may include transmitting an alert message upon power up after the outage to indicate a power restoration local to the device.
