Always leading the pack

Always leading the pack

Since the company's founding in 1868, we have always been a step ahead of the competition in terms of technology. Our inventions have caught on globally and set the standard in energy technology to this day. The VACUTAP® on-load tap-changer, TAPCON® voltage regulator, ETOS® transformer operating system, MTraB® intelligent dehydrating breather and TESSA® asset performance management are five examples from our innovative product range that set the standard globally and are therefore rightly sold under the MR brand.
