Non-Technical Losses on Injected Distribution Energy: Case Study on Entry Meters, Installed in the Rio De Janeiro State, Brazil

Abstract

Commercial or non-technical losses (NTL) on injected energy (regulatory) are primarily related to their fraud and theft in the distribution sectors, and corresponded to the concessionaires installed in Brazil, about 3.46% between 2010 and 2014, or values around US$ 300 million. For the region of Rio de Janeiro, these were, between 2010 and 2013, in the order of 11%. In order to reduce the amount of fraud in the concession area of the region in a case study, the use of drilling tools, the use of magnetic fields for blocking or delaying the meter disk, changes in the terminal contacts, such as electric bridges; the inverted connections of the internal circuits, the lack of neutral, by up to 12% each.
