Scope

1.1 This Part specifies the technical requirements, test items, marking and packing
of the excitation systems for synchronous electrical machines and phase modifiers and
it applies to the excitation systems for those 10MW and above hydraulic generators,
50MW and above turbine-type synchronous electrical machines and phase modifiers
that are connected with power system. The excitation systems for generator motors
also may be used by making reference thereof.
1.2 This Part only applies to the excitation systems of the following types:
1.2.1 Excitation system with AC exciter
a) AC exciter with stationary rectifier;
b) AC exciter with rotating rectifier (brushless excitation system).
1.2.2 Static excitation system
a) Potential source static excitation system;
b) Compound source static excitation system.
