what is static excitation and dynamic excitation of
synchronous generator,scr excitation is a brush or
brushless excitation?

Answer Posted / elec_maint

Both static and dynamic exciters, may use solid devices as
AC/DC converters. The key difference is that static type
feeding the field winding (F.W) via brushes, but in the
dynamic one the solid state converter is rotating with the
F.W, and the supply to the converter is induced from
external excitation stator windings.
