What's field excitation in an electrical system

What's field excitation in an electrical system

Nov 12, 2017 What's field excitation in an electrical system? A field relay in the GCU (generator control unit) allows or prevents field excitation within the generator. When open, the field relay deprives the associated power relay of its ground, which causes the power relay to open. It's an excerpt from the Citation M2's pilot training manual.
