Figure 198: Relay characteristic angle given in degree
In a transmission network a normal value of RCA is about 80°.
VPolMin: Minimum polarization (reference) voltage % of VBase.
I>Dir: Operate residual current level for directional comparison scheme. The setting is
given in % of IBase. The pickup forward or pickup reverse signals can be used in a
communication scheme. The appropriate signal must be configured to the
communication scheme block.
