The Alexanderson alternator

 

 

The Varberg Radio Station at Grimeton in southern Sweden (built 1922-24) is an exceptionally well-preserved monument to early wireless transatlantic communication. It consists of the transmitter equipment, including the aerial system of six 127-m high steel towers. Although no longer in regular use, the equipment has been maintained in operating condition, including the original Alexanderson alternator.

The site is an outstanding example of the development of telecommunications and is the only surviving example of a major transmitting station based on pre-electronic technology.

The Alexanderson alternator is on the list of IEEE Milestones as a key achievement in electrical engineering.
