Excitation Power
Excitation power is wired to the PMG terminals, whether connected to the
generator output (Shunt Excited) or to a PMG. Connect shunt excited inputs
with a voltage transformer (VT).
PMG inputs are on TB1 and are labeled PMG A, PMG B, and PMG C,
illustrating their respective phase relationships. Single-phase excitation power
must be connected to terminals PMG A and PMG C. Twisted, shielded cabling is
required for the PMG inputs.
Refer to the wiring diagrams below.
