Abstract

Technical irregularities found in electrical power meters due to tampering, which are classified as fraud, are responsible for the most part of the energy loss experienced in the sector of electrical power distribution. The cost of energy theft is shared with all consumers in the form of non-technical losses. This work suits that context, by means of combating fraud in electric power meters in order to reduce losses due to the strengthening of effective punishment of cheaters. For that is proposed a systematization model of the process for verification of irregularities in electric power meters and the respective issuance of audit reports. The proposed systematization is based on a database containing standardized irregularities which were hierarchically arranged and also from information obtained from metrological calibration audits, thus ensuring the reliability of the results. The proposed model was tested in samples of tampered power meters provided by the electrical distribution utilities in southern Brazil. A main outcome of this research is a customized software that organizes the procedures of technical audit in a legally binding basis as applied to power meters. From the results of analysis conducted on sample power meters audited, it was possible to settle the software's report.
