Evaluation of Radiometric Localization Techniques Based on the Intensity of the Received Signal

This paper presents an analysis of the efficacy of radiometric localization techniques for partial discharges sources, utilizing received signal strength. Tests in experimental setups with dimensions ranging from <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$2\times 2\ \mathrm{m}$</tex> to <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">$6\times 4\ \mathrm{m}$</tex> with two different sources to emulate the phenomena were employed: a controlled source and an oil cell. In addition, the envelope detection was evaluated for this purpose. The techniques based on amplitude made the detection and localization of PD sources more practical and feasible. The location errors are around 0.25 m indicates that these techniques are promising and could help to reduce the costs associated with partial discharges monitoring processes.
