How an unassuming technical principle from Regensburg made modern power supply possible – and why its legacy is more important than ever in the age of the energy transition
This advertorial from Reinhausen looks back at 100 years of the Jansen patent and the high-speed resistor-type tap-changer, an invention that quietly helped make stable power grids possible. It explains how this principle shaped modern voltage regulation and how its legacy continues through today’s tap-changer, digital monitoring, and asset management solutions.
