Patent ID: 8817428

Claim:
A method of monitoring temperature in an electrical distribution system for transmitting electrical power generated by a utility company, the method comprising: receiving from a first sensor a first set of temperature signals indicative of a temperature of a first electrical-power-transmitting device in the electrical distribution system over a predetermined period of time; receiving from a second sensor a second set of temperature signals indicative of a temperature of a second electrical-power-transmitting device in the electrical distribution system over the predetermined period of time; determining a first rolling average temperature for the first device for the predetermined period of time from the first set of temperature signals, the first rolling average temperature including a first series of averages comprising a respective average for each of a plurality of subsets of temperature signals within the first set of temperature signals; determining a second rolling average temperature for the second device for the predetermined period of time from the second set of temperature signals, the second rolling average temperature including a second series of averages comprising a respective average for each of a plurality of subsets of temperature signals within the second set of temperature signals; and triggering a disconnect event in response to a determination that either the first rolling average temperature or the second rolling average temperature is greater than a predetermined maximum working temperature.
