Description: No theory describes physical reality absolutely. Engineering has the important role of finding correspondences between theory and reality, between theoretical models and physical or material models.
From the point of view of theoretical models, the macroscopic theory of electromagnetic phenomena is a phenomenological theory, independent of any microscopic model. This theory abstracts from the discrete structure of materials, material models (bodies) being considered continuous media.
The classical Maxwell-Hertz macroscopic theory is the basis of the main technical applications of electromagnetic phenomena in the field of strong currents. It allows the simple and relatively precise solution of electrotechnical problems being a powerful tool at the hands of engineers.
In Electrical Engineering, in order to solve the complex and rapidly evolving technical challenges regarding the efficient use of electrical energy, optimal and economical solutions must be found. The profile industry has developed equipment, appliances and technologies that cover the needs of domestic and industrial uses.
The book Efficient use of electrical energy – Theory and applications, bridges the gap between the theory of electromagnetic phenomena and some practical solutions to make the use of electrical energy more efficient.
Notes: If you work in the field of Electrotechnics, it is difficult to share, through a single book, the results of experience accumulated over decades of activity. In this book, I modestly try to present, theoretically and practically, solutions to some technical situations encountered, offering effective solutions to eliminate energy losses.
Both by content and by the accessible way of treating the problems addressed, the book is addressed, first of all, to engineers in the electrotechnical field, being at the same time a useful support for specialists interested in choosing optimal solutions from the point of view of reducing costs electricity consumption
