 (1) Functions
 (a) Generator CT The generator CT is used for differential and overcurrent protections (Ref. Para. 4.A.(2) Generator control and protection functions).
 (b) Six-hole CT The six-hole CT contains six toroidal transformers, one for each of the parallel power feeder cables. The six-hole CT is connected in electrical opposition to the CT of the IDG generator. This CT is used for differential and open cable protections (Ref. Para. 4.A.(2) Generator control and protection functions).
 (c) Three-hole CT The three-hole CT contains three toroidal transformers, one for each of the power feeder cables.

 A. Generator Control
 Controls and indications for each generator are located on the overhead
 panel in the cockpit. The signals to and from the indicators and controls
 transit by the GCU.
