New leaflet on grid protection
A leaflet is now available on SuperGrid Institute’s resistive superconducting fault current limiter (RSFCL), which is a grid protection technology providing an ultra-fast passive response to prevent the propagation of high over-voltages in AC and DC networks. System protection also represents the focus of SCARLET’s WP5 and has seen a lot of progress recently, as highlighted on SuperGrid’s dedicated webpage.
The innovative design of the RSFCL demonstrator is based on a series of 10 pancake coils of superconducting tape in a cryostat where the liquid nitrogen has been brought down to 68 Kelvin (-205°C). SCARLET’s Christophe Creusot, who leads WP5, explains: “Cryogenics can be a daunting prospect in the world of electricity. But it’s a perfectly autonomous system where the machine generates its own liquid nitrogen and works in a closed circuit. There is redundancy, even in the event of a breakdown, and these systems have been in use for several decades in other industries, such as gas liquefaction, maritime transport of liquefied gases, food processing and pharmaceuticals.”
