Internship – Dielectric and thermoelectric simulations applied to fault current limiters

Posted 2 months ago

SuperGrid Institute brings together 180 employees, of 28 different nationalities who work together within a dynamic environment in the city of Lyon. As an independent research and innovation centre, we are dedicated to developing technologies for the future power transmission system, the “supergrid”, including HVDC & MVDC technologies.

As a multi-disciplinary research centre with advanced simulation capabilities & multiple test platforms, including numerous associated laboratories, SuperGrid Institute uses its comprehensive expertise to provide a wide range of services and solutions to support our customers in developing power systems, equipment and components. We specialise in system architecture and work on ensuring network security and stability while allowing for the integration of intermittent renewable energy sources.

General Context

SuperGrid Institute is developing a novel device, the fault current limiter. Based on superconducting materials, it reduces the intensity of fault currents and facilitates the fault clearance. To do so, Supergrid Institute disposes of a cryogenic platform, a real size fault current limiter prototype, a high voltage test laboratory and a high-power test platform.

Objectives / Missions

The objective of the internship is to develop our simulation tools and use them to:

  • Establish a set of rules for the dielectric sizing of a fault current limiter
  • Evaluate the intensity and the impact of temperature inhomogeneities during a current limitation.


  • Consolidate a finite element model (FEM) of the dielectric environment of a fault current limiter in a gaseous and liquid medium (nitrogen).
  • Establish an analytic model, based on simulations, for the dielectric sizing of a fault current limiter.
  • Application of the dielectric sizing for fault current limiters operating at different voltage levels.
  • Consolidate a thermo-electric model (FEM) of a multilayer superconductor tape immersed in liquid nitrogen during the superconducting – normal transition.
  • Compare the FEM results with our experimental data.

The internship will take place in the “High Voltage Substation Equipment” program. Regular meetings will be conducted within the project team.
