an approach to life estimation of Electrical Plant components in the presence of harmonic distortion
International Conference on Harmonics and Quality of Power, 2000Co-Authors: P Caramia, G Carpinelli, P Verde, G Mazzanti, A Cavallini, G C MontanariAbstract:Harmonic distortion can affect significantly the reliability of Electrical Plant components by increasing the degradation rate of Electrical insulation. This paper presents life models which enable estimation of failure times of the Electrical insulation of the main components of industrial Electrical Plants, i.e. capacitors, cables, motors and transformers, when the prevailing aging stresses are voltage and temperature and harmonics give rise to considerable voltage and current distortion. The models are inserted in a probabilistic framework, which accounts for the inherently random nature of harmonics. It is shown that the degradation rate can become much larger than in the sinusoidal case, especially due to the contribution of harmonics to voltage peak magnification: also current distortion can play an important role. Hence, significant life reduction can be expected in the components which are subjected to harmonics.

data mining techniques to assess the condition of high voltage Electrical Plant
Set of Papers Presented to the CIGRE 2002 Session No 39:, 2002Co-Authors: A Mcgrail, E Gulski, E Groo, David Alla, David Irtwhistle, Trevo LackbuAbstract:Increasing demands to fully exploit the capabilities of existing transmission equipment and systems require the best use from data assets in corporate databases and also require the development of new and comprehensive diagnostics for high voltage equipment. Data Mining allows extraction of new information or knowledge and development of new methods for visualising and analysing the data held. Consequently, data mining should be seen as part of a well-considered information and asset management strategy. This paper outlines some work which has been done to achieve such optimal use of diagnostic data on modern Electrical Plant. Two variations of data mining approaches are discussed using examples from different diagnostic measurements and tests. The use of Kohonen mapping applied to existing and new data is illustrated using examples of dissolved gas analysis, tap-changer monitoring and insulator testing. In addition, two other examples are given illustrating the potential for data mining to produce useful information from comprehensive modern diagnostic monitoring of high voltage cables and of circuit breakers. A new task force within SC15 has been established to embark on a coordinated and focussed approach to develop guidelines for data mining in practice.
