For the 8-Bit Comparator at UR-2
1. Remote power from UR-1 IED received on direct inputs is the first argument for the comparator. As such, apply the
following settings:
8 BIT COMP 1 ARG A0
8 BIT COMP 1 ARG A4
8 BIT COMP 1 ARG A1
8 BIT COMP 1 ARG A5
8 BIT COMP 1 ARG A2
8 BIT COMP 1 ARG A6
8 BIT COMP 1 ARG A3
8 BIT COMP 1 ARG A7
2. Local power from the UR-2 IED available internally is the second argument for the comparator. Thus, apply the
following settings:
8 BIT COMP 1 ARG B0
8 BIT COMP 1 ARG B4
8 BIT COMP 1 ARG B1
5
8 BIT COMP 1 ARG B5
8 BIT COMP 1 ARG B2
8 BIT COMP 1 ARG B6
8 BIT COMP 1 ARG B3
8 BIT COMP 1 ARG B7
3. The two power values are to be added, therefore set
4. To establish the alarm when the total power in either direction (import or export) is above the threshold, set

display, set

actual values represent the remote (UR-1), local (UR-2), and total power values in MW.
7. To set the alarm when the total power is greater than 2500 MW, set
8. To clear the alarm when the total power is less than 2000 MW, the hysteresis setting needs to be at 2500 – 2000 = 500
