Identification of energy theft and tampered meters using a central observer meter: a mathematical approach

This paper presents a new methodology to identify energy theft and tampered meters as well as meters that are not working properly. It is based on a central observer meter that is responsible for metering the overall energy of a group of consumers under investigation. Deterministic and statistic approaches are used to determine which consumers have problems in their premises. Also, pattern recognition is used to discover energy theft using bypass.
