They investigated that the large turbo-generators under excited operation are affected due to modern amplidyne voltage regulators.
For instance, in one realm, Alexanderson saw common principles in electronic amplification and the amplidyne (dynamo amplifier); in the other, he likened the economics of electric utilities (central stations, load management) to those of radio broadcasting.
