SuperGrid Institute at CIGRE Technical Exhibition

2018-08-10T10:37:50+00:00August 9th, 2018|All, Conference, Event|

From 27 to 31 August, SuperGrid Institute participate at the CIGRE Technical Exhibition 2018: the leading Power Systems Event. Posters, workshops, sessions… you will meet many of our SuperGrid Institute experts, and of course at our stand n°243, available to network and discuss.

A High Current Switching test bench to estimate switching losses for power switches

2018-08-09T17:43:58+00:00July 27th, 2018|Power Electronics & Converters|

Our High Current Switching test bench is now operational! This one is integrated to the Power switches characterization platform, which can be used to fully characterize power switches.

An injection molding press for our Chemistry & Materials test platform

2018-08-09T17:44:00+00:00July 13th, 2018|High Voltage Substation Equipment, HVDC Cable Systems|

With a new semi-automatic injection mixer and an injection molding press, the material characterization and the processing of our samples will take less time – close to industrial production thanks to the Automatic Pressure Gelation (APG) method.

High Voltage Electrical Properties of Epoxy / h-BN Microcomposites

2018-08-09T17:44:02+00:00July 4th, 2018|High Voltage Substation Equipment, Publications|

Two high voltage properties – DC conductivity and AC breakdown strength – of epoxy composites filled with 30 wt% of micron sized hexagonal boron nitride (h-BN) are discussed in comparison to neat epoxy.

Testing phase after installation of SuperGrid Institute’s hyperbaric vessel

Our 10 tones, six meters long, hyperbaric vessel has been installed at our premises and is now going through final tests before commercial use.

PhD Benoît TEZENAS du MONTCEL “Experimental study and modelling of a metal vapor plasma in a vacuum chamber for the development of High-Voltage Circuit Breakers”

2018-08-09T17:44:04+00:00May 29th, 2018|All, High Voltage Substation Equipment, Phd|

The study involves first the building of an experimental setup where arcs, created between two fixed CuCr25 contacts, were visualized using a high-speed camera in a vacuum demountable chamber.

A novel hyperbaric vessel for SuperGrid Institute

2018-08-09T17:44:05+00:00January 29th, 2018|High Voltage Substation Equipment, HVDC Cable Systems|

Since 2016, SuperGrid Institute’s program 4 has intensely worked on the specification of a test platform with the capability to go up to 40bars of internal pressure and validate subsea node, a SuperGrid Institute concept for offshore meshed networks. Beside its imposing size, the particularity of this platform is that it allows combined testing functions on subsea high-voltage cable systems including water pressure, di

PhD William LEON GARCIA “Protection strategy for HVDC networks”

2018-08-09T17:44:07+00:00January 26th, 2018|All, Phd, Supergrid Architecture & Systems|

Multi-terminal high voltage direct current (MTDC) grids, or supergrids, are considered an interesting solution to integrate large amounts of renewable power and release congestion of existing AC power grids. Nonetheless, safe and reliable operation of such grids require the development of new DC protection systems.
