Expertise

One discipline, mastered completely.

Simulation, measurement and shielding are not separate services. We combine all three in a single engineering loop — which is why our predictions hold and our shields are never over-dimensioned.

Magnetic Shielding

Mu-metal, electrical steel and conductive shields engineered for up to 40 dB attenuation.

3D Simulation

Validated finite-element models predicting flux density before anything is built.

Field Measurements

Calibrated three-axis campaigns, long-term monitoring and interference diagnostics.

ORNI / NISV Compliance

Authority-ready dossiers for the world's strictest precautionary limit regime.

Equipment Protection

Ultra-low field environments for electron microscopes, MRI and metrology.

Mitigation Engineering

Phase optimisation, routing, compensation loops — physics before material cost.

Simulation

We know the field before it exists.

Every project starts with a 3D model of the real installation: conductors, phase arrangement, load cases, structural steel. The result is a flux density map accurate to within roughly 10% of the commissioning measurement.

  • Compliance forecast at design stage
  • Cost-ranked mitigation variants
  • Authority-ready documentation
  • Verification measurement closing the loop

Shielding

Materials chosen by physics, not by catalogue.

Mu-metal, amorphous alloys, electrical steel, aluminium and copper — layered for the exact frequency and geometry. Prefabricated in Switzerland, installed by our own supervisors anywhere in the world.

Software

EDISON Magnetic Field Simulation Platform

Our in-house platform for 3D visualisation and simulation of MV/LV stations, HV substations, overhead lines, cable routes, busbars and technical buildings — developed and validated over three decades of field projects.
