VrLV 400.0 Rated LV side AC voltage (in Volts)
VrHV 18.00 Rated HV side AC voltage in kV
PhAngleShift 150 5*30= 150 degree, this provides 150
degrees clock-wise phase angle shift
across the excitation transformer
Note that last three parameters from the table above have no direct influence on
function operation (that is, LV side CT is used) but are anyhow set to the correct
values.

MeasurCurrent DC In order to measure directly rotor
winding DC current
IBase 1520 Rated current of the field winding (i.e.
field current required to produce rated
output from the stator)
CT_Location HV_winding HV side 100/5 CT used for
measurement
VrLV 550.0 Rated LV side AC voltage (in Volts)
VrHV 11.00 Rated HV side AC voltage in kV
PhAngleShift -30 11*30-360=-30 degree, this provides
30 degrees anti-clock-wise phase
angle shift across the excitation
transformer
Note that last three parameters from the table above must be properly set in order to
have proper operation of the rotor overload function.
The rest of the parameters can be set with the default values, if the generator is
fabricated according to IEEE-C50.13. The parameters have to be changed according to
the specifications, if different standards are applicable.
The parameters for the Generator rotor overload protection GRPTTR (49R) are set via
the local HMI or PCM600.
