Test Results of a 100 kA NbTi CICC

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche

For the secondary winding of the flux pump (superconducting transformer) of the EDIPO test facility at CRPP Villigen, a NbTi cable-in-conduit conductor (CICC) was designed at CRPP and procured at the industry. From a left section of the CICC a SULTAN sampl ...

MV Power Grids Integration of a Resistive Fault Current Limiter Based on HTS-CCs

Bertrand Dutoit, Bertrand Dutoit, Daniele Colangelo

Due to the energy demand growth and distributed generation (DG) units penetration, a substantial increase of the rated short-circuit current of the electrical lines is expected. As a consequence, the electrical grid infrastructure needs to be extended or d ...

Operation and Test Results From the SULTAN Test Facility

Pierluigi Bruzzone, Boris Stepanov, Rainer Wesche, Stephen Alfred March, Ciro Calzolaio

In the period between August 2010 and August 2011 the SULTAN test facility has been continuously operated, with over one dozen test campaigns. Among the ITER conductors, five Toroidal Field (TF) samples, two Central Solenoid (CS) samples and four NbTi samp ...

Study on the Reversible DC-DC Converter as Interface between Low and Medium Voltage DC Networks

Alfred Rufer, Stephan Kenzelmann, Carlo Arrioja

This paper introduces an isolated reversible DC-DC converter with a particular topology, which benefits from both the NPC (neutral point clamped) structure and the series-parallel connection of converters. The key property of the proposed topology is the o ...
