The influence of generator voltage regulators upon powerline stability is closely scrutinized by analog techniques. Contrary to common concepts, it is shown that high-speed control of excitation to maintain constant terminal voltage actually hampers

Oscillations which developed on the initial transmission tie between the Northwest and Southwest systems brought about trip-outs and threatened to limit its usefulness. The analog study described reveals much about the nature of the oscillations and
