Abstract:
1. A method of monitoring and controlling an operation of a meter electrically connected between a power source and a load, comprising: periodically detecting a first temperature of a first location with a first sensor and detecting a second temperature of a second location with a second sensor; processing the first temperature and the second temperature; comparing at least one of the first temperature and the second temperature to a first threshold for transmitting an alarm and a second threshold for operating a remote disconnect switch to disconnect an electrical connection of the power source; comparing the first temperature and the second temperature to determine a first temperature difference; determining a short-term temperature average of at least one of the first temperature and the second temperature over a first number of samples; determining a long-term temperature average of the at least one of the first temperature and the second temperature over a second number of samples; determining an average rate of change based on the short-term temperature average and the long-term temperature average; and modifying at least one of the first threshold and the second threshold when it is determined the first temperature difference is equal to or greater than a third threshold and the average rate of change is equal to or greater than a fourth threshold.
