Setting data entered here are the various measured or calculated impedances and
resistances of the protected line section. This data may be physically measured or taken
from computer simulation studies of the Line segment. For example the parameters
R1A and X1A are the resistance and reactance in reverse direction, the parameters R1B
and X1B are the resistance and reactance in the forward direction. These parameters
along with the others found here need to be given values. For complete parameter data
refer to the Technical reference manual (TRM).
