To effectively manage the substantial energy contained within superconducting magnets, especially during quench events, Tokamak magnetic systems need to be equipped with extremely robust protection mechanisms. In a pioneering move within the realm of Fusion Research, DTT (Divertor Tokamak Test Facility) has introduced Metrosil silicon carbide (SiC) varistors, marking a significant advancement in high energy quench protection. These matched banks …
Co-authored with scientists and engineers from CERN and DTT, our latest paper published on IEEE Xplore covers the thermal effects on the electrical properties of Metrosil Varistors during high energy discharges. This work is key to understanding the Metrosil performance during a discharge from a large superconducting magnet, such as those found in fusion tokamaks, and the paper continues a …

ENEA, Italy’s National Agency for New Technologies, Energy and Sustainable Economic Development and its partners have specified …
Metrosil, the world’s leading brand of silicon carbide varistors, which protect critical infrastructure around the world, including the world’s biggest hydroelectric dams, is celebrating 85 years of production. “Metrosil’s properties and composition are what makes it incredibly useful for critical fault protection. It’s certainly stood the test of time and has always been very ‘current’; not only will you find …
UK-based surge protection manufacturer Metrosil has completed the shipping of high energy silicon carbide varistor systems to protect China’s Three Gorges Corporation (CTG) 16GW Baihetan hydropower plant from unexpected power surges and de-excitation. The order of Metrosil 8000 Series began delivery to the Baihetan construction site in January 2021 and will complete the supply of Metrosil varistors across the world’s …
We appreciate that many of you will be working remotely right now – some of you may even be self-isolating at your place of work! That is why we are hosting a number of short webinars aimed at power network reliability. Our first session, “Overvoltage Protection: Keeping the Lights on”, will take place on Tuesday 26th May at 4pm BST …
The Financial Times has named M&I Materials technical Director, Dr Amanda Quadling, as one of the UK’s top 10 ‘Most Influential Women in Engineering’ for 2019 in its final list of 100 candidates. The winners were announced after a thorough assessment process, conducted over a number of months after which the final ‘Top 10’ were selected by a judging panel. …
