Scope & Technical Coverage

AreaDetails
Modelling Frequency-domain solution with ground-return; mutual coupling among overhead lines, underground cables, rails, pipelines; realistic bonds, screens and terminations.
Use Cases Rail electrification & stray currents, pipeline interference, corridor co-location, plant EM exposure, HV/OHL–cable interactions, telecom co-routing.
Inputs Conductor geometry & routing, multilayer soil, load spectra or operating cases, bonding schemes, separation/clearances, shielding strategies.
Outputs EM field maps/profiles, induced V/I, transfer potentials, screening effectiveness, and compliance indicators versus ICNIRP/EN limits.
Integration Complements GSA/GSA FD for earthing, XGSA TD for time-domain studies, and NETS for multi-conductor networks to deliver end-to-end assessments.
