“…Losses of electric energy in the grid at level of transmission and distribution (T&D) encompass both technical losses and non-technical losses (NTLs) and for the estimation of the later is normally required the estimation of the former [1][2][3][4]. Technical losses are naturally occurring losses due to irradiation 5 and as a result of inevitable dissipation of electric energy into the equipment necessary for implementing T&D [1,4,5], involving losses in dielectrics and mostly in the conductors by Joule's effect.…”

This paper is a review of literature with an analysis on a selection of scientific studies for detection of non-technical losses. Non-technical losses occurring in the electric grid at level of transmission or of distribution have negative impact on economies, affecting utilities, paying consumers and states. The paper is concerned with the lines of research pursued, the main techniques used and the limitations on current solutions. Also, a typology for the categorization of solutions for detection of non-technical losses is proposed and the sources and possible attack/vulnerability points are identified. The selected literature covers a wide range of solutions associated with non-technical losses. Of the 103 selected studies, 6 are theoretical, 25 propose hardware solutions and 72 propose non-hardware solutions. Data based classification models and data from consumption with high resolution are respectively required in about 47% and 35% of the reported solutions. Available solutions cover a wide range of cases, with the main limitation found being the lack of an unified solution, which enables the detection of all kinds of non-technical losses.

“…In broad concept, there are four categories of electricity loss is expressed as fraud, directly stealing power, billing irregularities, and unpaid bills [1]. The technical loss is the electrical power dissipation occurs to due to the internal resistance and emission in end points, devices during power generation, transmissions and distribution process.…”

“…While the non-technical energy loss, which is also commonly term as NTL and considered as T&D loss (Transmission and Distribution Loss), can be determined by various type of methods. NTL is mainly due to the electricity theft fraud, stealing power (by any means or way), billing irregularities, and unpaid bills [1]. Now, in current circumstances, electricity is a key input in many production processes.…”

“…Hence its continuous supply is crucial. The biggest challenge for any underdeveloped or developed country around the globe is the prevention of electricity energy theft [1]. Energy theft not only the rising price in electricity charges but also influences on many other factors such as inflation, unemployment, load-shading, disturbs routine of industries, factories and other businesses, rise in debts of power energy companies, as well as having a high impact on economical state of country.…”

“…Recently, NTL reported that it covers up to 40% of total energy [2]. According to the JPS, of the 26.6 percent system losses registered in 2014, approximately 17.0 percentage points represent non-technical losses [1]. Specifically, in Pakistan, it was recorded around 17.03% of total energy which costs hundreds of billion dollars, as per the financial year 2013 [3].…”

The most essential asset of any country that can boost its development or can destroy it, is electricity. Electricity theft prevention or non-technical loss detection has become major problem around the globe for every developed or under develop country to maintain its status in global society. Every month and every year many researchers, scholars and university students presented their studies, ideas and proposed their electric management system for prevalent of nontechnical energy loss detection in transmission line. The core objective of this survey is to highlight the existing solutions, their effectiveness in terms of performance and accuracy and their applicability. This will help in finding a diverse and reliable solution, understanding what others possible methodologies and techniques can be adopted in order to overcome current transmission supply challenges and improve the existing solution that can promptly address electricity prevention issues.

Limits of energy access research on unreliability

Electricity users in sub‐Saharan Africa face persistent unreliable and unaffordable access. However, users' perspectives and experiences have largely been absent from policy literature. Content analysis of energy access policy literature reveals two long‐held assumptions: (1) any connection is better than no connection; (2) residents who object to this poor access have an entitlement problem. This paper critically interrogates these assumptions by using ethnographic data gathered during fieldwork in Unguja, Tanzania. It finds that long‐held policy justifications are easily contravened by real‐life experiences of sub‐par service and counters conventional narratives that blame users for the failure of electricity systems in their communities.
