Figure 6.2 shows how to enter the new map into the relay. Use the SET D
command and enter N at the prompts shown in Figure 6.2 to allow changes to
the existing maps. Press <Enter> at the line prompt to advance to the next
map. For example, press <Enter> at line 10 of the Binary Input Map to
advance to the Binary Output Map.

a
Assume the largest expected current is 2000 A, scale the analog value by a factor of 10 to
provide a resolution of 0.1 A and a maximum current of 3276.7 A. Report change events on a
change of 5 A.
b
Angles are scaled to 1/100 of a degree. Report change events on a change of 2 degrees.
c
For a nominal voltage of 230 kV, scale the analog value by a factor of 100 to provide a
resolution of 10 V and a maximum value of 327.67 kV. Report 1 kV for change event reporting.
d
For a maximum load of 800 MW (or 800 mVar), scale the power by a factor of 40 to provide a
resolution of 0.025 MW, and a maximum value of 819.175 MW. Report 1 MW for change event
reporting.
e
VDC1 is scaled by a factor of 1/100 of a volt. Report change events on a change of 2 V.
