Methodology, software & labs

How you'll learn

100% online training on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. No fixed timetable: students progress at their own pace within the intake, which makes it compatible with work.

Each module combines theory, guided reading of the original standard and applied exercises. The working software is ETAP, SKM PowerTools, EasyPower, Schneider Electric Ecodial, DIgSILENT PowerFactory, in free, academic or evaluation versions. The exercises work through real procedures for plotting and verifying time-current curves, selectivity studies in industrial installations and analysis of spurious trips. Assessment is continuous across modules, plus a final integrating project.

Accreditation-ready laboratories(EN ISO/IEC 17025) with a rotor rig, EMC/lightning pre-compliance, HIL/SIL, vibration/acoustics.
Evidence-driven final project:safety case, test plan, compliance dossier and operational limits.
Industry mentoring:lecturers with experience in la formacion, , eVTOL/UAM and flight test.
Flexible format(hybrid/online), international cohorts and support from SEIUM Career Services.
Ethics and safety:an approach built on safety-by-design, OT cybersecurity, DIH and compliance as core pillars.
