As transmission corridors grow more congested, electromagnetic and electrostatic induction studies are becoming critical for safe power system planning. These studies assess induced voltages and currents on nearby conductive objects — fences, pipelines, vehicles, structures — under normal operating conditions, not just fault events. Two mechanisms are covered: electromagnetic induction (magnetic field coupling) and electrostatic induction (capacitive coupling from electric fields). Detailed 3D modeling tools like SES/HIFREQ within CDEGS are used to capture geometry, soil resistivity, grounding configurations, and conductor loading. Results are evaluated against standards like IEEE C95.6, and mitigation options such as grounding, bonding, or shielding are assessed before field implementation.
