Electromagnetic Transients in Power Cables
2013For more than a century, overhead lines have been the most commonly usedtechnology for transmitting electrical energy at all voltage levels, especially on the highest levels. However, in recent years, an increase in both the number and length of HVAC cables in the transmission networks of different countries like Denmark, Japan or United Kingdom has ...

Balance of Electromagnetic Energy in Transients
2019Energy conservation is one of most fundamental rules in physics, which is interpreted as the input energy of any system is equal to the sum of the energy loss, storage and output.

Continuous Transient Electromagnetic Sounding
1st EEGS Meeting, 1995Steadily growing abstraction of ground water together with the impact of pollution from surface infiltration have increased the need for hydrogeological investigations of aquifers. The mapping of subsurface resistivity structures using electrical and electromagnetic methods has gained a central role in the set-up of hydrogeological models of catchments

Techniques for analyzing electromagnetic transients
IEEE Computer Applications in Power, 1997With few exceptions, power system electromagnetic transients must be studied on a three-phase basis rather than on a positive sequence single-phase basis. For example, the three-phase opening of a circuit breaker is no longer a symmetric event in the ms range.

Transient electromagnetic interference in substations
IEEE Transactions on Power Delivery, 1994Electromagnetic interference levels on sensitive electronic equipment are quantified experimentally and theoretically in air and gas insulated substations of different voltages. Measurement techniques for recording interference voltages and currents and electric and magnetic fields are reviewed and actual interference data are summarized. Conducted and

Chirality and the transient electromagnetic pulse
IEEE Antennas and Propagation Society International Symposium 1992 Digest, 1992The one-dimensional plane wave propagation of a transient TEM (transverse electromagnetic) pulse in a homogeneous isotropic chiral material is analyzed. Using asymptotic techniques the authors have derived expressions for the electric field at various times of interest and observed similarities and differences between transient responses in chiral and ...

Measurement and Observation of Electromagnetic Transients
2019Power electronic systems consist of interactions between the information and energy. To implement the effective energy propagation through the control system, the related energy-flow information needs be fed back to the control unit, i.e., measurement and analysis.

Electromagnetic transients in conducting media
IRE Transactions on Antennas and Propagation, 1960In a recent paper, Richards derives expressions for the electric and magnetic fields of a short pulse of electric or magnetic dipole moment in a conducting medium. An alternative analysis is given which explains certain unusual results of the original work as arising from dispersion in the conducting medium and from the frequency dependence of the ...

Digital simulation of electromagnetic transients
Electric Power Systems Research, 1997Abstract This paper presents the development of a new time domain simulation program for the computation of electromagnetic transients over a wide frequency spectrum. The application of the program to investigate the Subsynchronous Resonance phenomenon is given.
