Abstract
An electricity meter may include a plurality of current terminals and a temperature sensing circuit. The circuit has a first set of thermocouple junctions having a first observed polarity and a second set of thermocouple junctions having a second observed polarity that is opposite of the first observed polarity. Each of the first set and the second set are disposed adjacent to a respective current terminal so as to measure relative temperature changes at the respective current terminal Each of the first set and the second set are connected to each other in series such that when each of the current terminals are at the same temperature, the temperature sensing circuit has a net voltage of zero. Alternatively, when one or more of the terminals has a temperature that is different from the other terminals, the temperature sensing circuit has a net voltage that is greater or less than zero.
