123. In preparation for paralleling generators, if the electric plant condition is as shown by graph «A», what would be the rotational status of the synchronizing lamps as shown in circuit «B»

The incoming generator runs slightly faster than the bus, causing the synchronizing lamps to revolve slowly in the fast direction. This is because the incoming generator's phase is catching up to the bus, indicating a slightly higher frequency, and the small frequency difference results in slow rotation.
