The equalizing coils on voltage regulators will
- have current passing through them from the higher loaded generator to the lower.
- have current passing through them only when the generators are not paralleled.
- be connected to each other when the generators are paralleled.
Explanation
Equalising coils are cross-connected between the regulators only when the generators are paralleled, so any imbalance in load sharing drives an equalising current that nudges each regulator until the generators carry equal load. When a generator runs alone its equalising circuit is open and carries no current.
