Relays Are Interesting Too

Abstract

Although Rogowski only pursued his own scientific work and did not accept commissions for research or development, he had good connections to industry. He recommended me to the director of AEG’s transformer factory in Oberschöneweide near Berlin. His name was Dr. Stern and he later became a university lecturer. This factory needed someone to develop safety-relays, to protect power plants against short circuits in high-voltage transmission lines. Shorts like this could happen for many reasons, for instance, if a tree fell on a line. I went to Berlin in the spring of 1928.
