Abstract

Resistance values for a first time for respective areas of a plurality of electrical connections are generated. Respective normalized resistance values are generated from the resistance values. Respective temperature rise values for a second time for respective ones of the areas of the electrical connections are generated. An average temperature value is generated from the temperature rise values. Respective normalized temperature rise values for the generated temperature rise values are generated based on the average temperature values. An abnormal condition of at least one of the connections is detected responsive to the normalized temperature rise values and the normalized resistance values.
