摘要:Abstract: Detection of unauthorized consumption in the context of non-technical losses through installation of the smart meters, as a part of electricity Transmission and Distribution, became a challenge for every engineer to give their contribution in this direction. Distribution systems losses can be attributed to technical and nontechnical losses. The percentages of Transmission and Distribution losses have been quite high and they affect the economy and the Utilities of every country. This paper processed to utilize smart meters in order to decrease non-technical losses in the distribution network and contribute on economy development and well-being of population. The paper shows how the significant voltage drop in the distribution lines can be used for the detection of unauthorized consumption in the context of non-technical losses. Suggestions are practically illustrated in example.
