Course Objective

The Advanced Technical Seminar provides attendees a unique opportunity to acquire practical and up-to-date engineering knowledge, from the world's leading specialists and researchers, on how to study and design efficient and economical grounding and lightning mitigation systems. 

Whether you wish to protect a power system, plant or a nearby utility subjected to electromagnetic interference from power system faults, lightning or switching surges, this course will present pertinent principles for utility, industrial and various public installations, during steady state, fault and transient conditions, using realistic models of the environment.

Emphasis is placed on the demonstration of scientific concepts, using practical examples drawn from the extensive number of research projects and engineering studies conducted by SES researchers since 1978. Pertinent analytical derivations are included in an extensive Reference Manual made available to all course participants. One of the main goals of this course is to explain and eliminate many misconceptions, ambiguities and incorrect measurements, analysis and design techniques which still abound in the industry and are taught at some courses.


Course Outline

In Week 1, we cover the three modes of electromagnetic energization. Earth resistivity measurement and interpretation techniques will also be discussed, for uniform and multilayered earth (soils with two and more horizontal and vertical layers). The concept of soil model equivalence and soil layer resolution will be explained based on computer simulations. The analysis and design of simple and complex grounding systems made of arbitrarily oriented three dimensional conductors buried in multilayered soils will be discussed and illustrated with practical examples. The case of a grounding system partially buried in a finite volume (e.g., backfill) of heterogeneous soil will be explored. The scientific concept of earth impedance measurements using the Fall-of-Potential method will be clearly explained based on various realistic soil models. Transmission line, buried cable and buried pipeline parameters (self and mutual impedances) in layered earth will be analyzed and fault current distribution computation techniques will be described. Electrical safety concepts will be introduced, and issues related to body currents, body impedances and foot resistances will be discussed for power frequency and high frequency electric exposure.

During Week 2, the focus is on demonstrating how to use SES’s powerful input and output processors such as SESCAD, RowCAD and SESShield-3D. Week 2 also includes conductive and inductive interference effects caused by energized conductors on overhead and buried bare or coated metallic structures and conductors, such as pipelines, fences and communication wires are introduced and investigated in detail. Mitigation methods and equipment are presented and their relative merits are discussed. Interaction between the sources of the interference and the victim lines or circuits will be examined in detail. Finally, electric and magnetic fields generated by energized overhead and buried conductors at low and high frequencies as well as during transient conditions, such as lightning strikes, will be described and typical analysis methods and computation results explained.
