Metrosil Varistors during high energy discharges

IEEE publish the latest technical paper on Metrosil Varistors during high energy discharges

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’s Divertor Tokamak Test (DTT) Facility to use Metrosil energy extraction and overvoltage protection

Each set of protection Metrosil’s will extract 684 MJ, at a nominal current of 42.5 kA while clamping overvoltages at 5.1 kV (Manchester, UK, August 2023), Specialist electrical protection equipment is to be deployed on a new fusion energy project in an industry-first. ENEA, Italy’s National Agency for New Technologies, Energy and Sustainable Economic Development and its partners have specified …

Metrosil Webinar: Protecting Current Transformers Against Open Circuit Conditions

Metrosil will be hosting a live 20-minute webinar on the 15th June 2022 to look at the impact of open circuit conditions on current transformers and how some methods of protection may not always be suitable, or sufficient, to avoid the damage and operational continuity of the high-value assets they protect. How will attendees benefit? Using industry expertise and reference …

Metrosil Celebrates 85 Years of Production

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 …

Protecting the World’s Largest Hydropower Generators

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 …

Metrosil Webinar: Keeping the Lights on

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 …

Protecting a powered-up tomorrow

The world is electrifying at a rapid pace. Whether it’s a developing country delivering power to underserved communities for the first time, or the era of the internal combustion engine (ICE) giving way to electric vehicles (EVs), tomorrow is powering up. Even industries that are already significantly electrified, such as rail, look to energy-intensive technologies such as maglev or hyperloop …

Metrosil Hosts BCC as it Demonstrates the Value of Ceramic Science to UK Manufacturing

Metrosil, manufacturer of globally recognised silicon carbide-based ceramic varistors, recently hosted Dr. Laura Cohen, Chief Executive of the British Ceramic Confederation. Dr. Cohen toured the manufacturing facilities and met the team at M&I Materials, where Metrosil is one of four advanced material streams within this private, export-led company. M&I Materials’ Technical Director, Dr. Amanda Quadling, who recently joined the BCC …
