Methodology, software & labs

How you'll learn

A 100% online programme on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: students progress at their own pace within the intake, which makes it possible to combine study with work.

Each module combines theory, guided reading of the original standard and applied exercises. The working software is ETAP, DIgSILENT PowerFactory, CAPE, OMICRON Test Universe, SKM PowerTools, in free, academic or evaluation versions. Tests are studied using real procedures from protection coordination studies, relay testing with injection test sets and analysis of oscillography records. Assessment is continuous by module, plus the final integrating project.

Accreditable laboratories(EN ISO/IEC 17025) with rotor test bench, EMC/Lightning pre-compliance, HIL/SIL, vibration/acoustics.
Evidence-oriented final project:safety case, test plan, compliance dossier and operational limits.
Industry mentoring:lecturers with experience in training, , eVTOL/UAM and flight test.
Flexible format(hybrid/online), international cohorts and support from SEIUM Career Services.
Ethics and safety:safety-by-design approach, cyber-OT, DIH and compliance as core pillars.

Frequently asked questions

The programme comprises 800 hours in total, spread over 6 to 8 months. That averages between 10 and 15 hours per week, compatible with a full-time job.

The work is carried out with ETAP, DIgSILENT PowerFactory, CAPE, OMICRON Test Universe and SKM PowerTools. Free, academic or evaluation versions are used, and the tutor indicates the free alternative where one exists.
