摘要： An electronic electricity meter (102) for monitoring electrical power consumption due to a plurality of loads, comprising electric power sensor (506A, 506, 502, 504, 508) configured to register, optionally in a substantially real-time fashion, data indicative of aggregate power demand (202) of a number of loads coupled to a common electrical power source, such as one or more phases of a polyphase system, load tracker (506B, 506, 502, 504) configured to detect the effect of individual loads on the basis of distinctive load patterns in said data, wherein the tracker is configured to utilize a distinctive load pattern detected in said data as at least a basis for a reference pattern (304, 306, 308) for subsequent detections (304a, 306a, 308a) of the effect of the same load in the data, accuracy analyzer (506C, 506, 502, 504) configured to, on the basis of comparisons of subsequent detections with the corresponding references, determine (312, 314, 316) whether the comparisons relating to at least two, preferably three, loads each indicate the difference between the subsequently detected pattern and the corresponding reference exceeding a predetermined threshold, and notifier (506D, 506, 502, 504, 508) configured to send, provided that positive determination has taken place (318), a notification signal indicative of potential fault with the electricity meter towards an external entity (106, 108). Corresponding arrangement and method are presented.
