The electrical department of the Ganz factory was organized by Zipernowsky, where he became a pioneer in the Hungarian electric industry. Within only a few months at the factory, his self-created arc lamps and dynamo were tested in the foundry’s electric system. That same year, the ice skating rink in Budapest installed the same lamps.
In 1883, Zipernowsky and his fellow colleague Miksa Déri invented the alternating current transformer. In 1889, they also patented their multiple-phased electric power distributer.
