Unified MoM-based electromagnetic modeling of grounding systems across all frequencies

Diverse and sometimes contradictory modeling approaches have left engineers without a consolidated resource for electromagnetic analysis of grounding systems. Electromagnetic Modeling of Grounding Systems unifies this research for the first time, presenting a computational framework applicable from DC through high frequencies exceeding 100 MHz and for lightning transients.

The book follows a structured approach, progressing from full-wave to low-frequency and quasi-static to DC models using MoM-based circuit-theory procedures for grounding analysis instead of traditional electromagnetic approach. With coverage of interrelations among quasi-static, circuit, hybrid, and full-wave methods, the author describes the integration of MoM with SPICE and EMTP circuit programs. Engineering analysis of harmonic and transient characteristics of various grounding configurations is presented, alongside design guidelines to optimize lightning-surge performance.

Readers will also find:

• Detailed MoM implementation for arbitrary electrode networks in uniform and two-layer soil, and their representation by equivalent circuits
• Original unpublished material on the development and application of new models and revised MoM representation extending current state-of-the-art computational approaches
• Computation of harmonic and transient impedance, step and touch voltages, transferred voltages, and electromagnetic fields for safety analysis
• Clear comparisons among quasi-static, circuit, hybrid, and full-wave modeling approaches that resolve existing confusion in the literature

Electromagnetic Modeling of Grounding Systems serves practicing electrical engineers in power system transients, surge and lightning protection, and EMC design. It is equally suited for graduate students in electrical engineering and researchers developing computational tools for safety, power quality, and electromagnetic compatibility of grounding and connected electrical systems.
