"A global approach of electromagnetism dedicated to further long-term planning"

Abstract : In order to provide a vision of power electrical engineering for future energy-supply crossroads and challenges, quasi-static laws of electromagnetism are obtained from variational principles deduced from thermostatistics by assuming a trend for a reversible evolution of the electromagnetic field. The approach provides a multi-scale framework suitable to derive electro-dynamical properties, from scratch to the design level. The actual trend to which obeys the electromagnetic field provides a dynamic representation of the power transmission and gives an insight to introduce the level of reliability in a sustainable planning.
