Claim Text:
1. A system with voltage regulator bypass, comprising: a voltage regulator comprising at least one transformer and a tap changer; a bypass switch coupled to the voltage regulator, and between a source and a load at a bypass contact, the bypass switch comprising a source disconnect contact, a load disconnect contact, and an actuator, the bypass switch further comprising a first state and a second state, wherein the actuator only permits the bypass switch to be in one of the first state and the second state, a bypass switch controller coupled to the bypass switch, wherein the bypass switch controller controls whether the bypass switch is put into the first state or the second state; and a logic controller coupled to the bypass switch controller, wherein the logic controller prevents the bypass switch controller from actuating the actuator that moves the bypass switch from the first state into the second state unless one or more bypass conditions are met, wherein the one or more bypass conditions include that the logic controller has received a signal from a neutral position switch indicating a movable contact of the tap changer is in a neutral tap position.
