Elgerd: Electric Energy System Theory: An Introduction, 1971, p. 322. 1. Fly ball speed governor: This is the heart of the system which senses the change in speed (frequency). As the speed increases the fly balls move outwards and the point B on linkage mechanism moves downwards. The reverse happens when the speed decreases. 2.
