Didier Empain

Didier Empain joined ENGIE Lab Laborelec in 1998 after completing his studies as industrial electrical engineer. He is an expert in electrical protection of power systems and power quality. He has completed a multitude of technical projects for various grid operators and industrial companies all over the world. Didier is known for his hands-on approach and his capability to combine his all-embracing expertise in high, medium and low voltage networks to come with smart and effective long-term solutions.



This intermediate level course provides participants with a solid understanding regarding protection of medium voltage grids. In addition to the basic concepts of grid protection, the following topics are also covered in detail: common fault types, neutral grounding, protection of cables and lines and protection of transformers. Simplified techniques for calculating short-circuit currents are also presented. Finally, the course also focuses on the impact of decentralized electrical production on the grid, and on its behavior in case of default.


The following aspects will be addressed during the training:

  • Defect types
  • Simplified calculations of short- circuit current
  • Measuring transformers
  • Basic concepts (selectivity, reliability, …
  • Neutral grounding
  • Protection types and applications
  • Conductor protection
  • Transformer protection
  • Decoupling protection
  • Evolution of protection technologies.
  • Introduction to IEC 61850

Target Audience

Maintenance and Operation technician and engineers.
