Figure 284: Relay characteristic angle given in degree
In a transmission network a normal value of RCA is about 80°.
UPolMin: Minimum polarization (reference) voltage % of UBase.
I>Dir: Operate residual current level for directional comparison scheme. The setting is given in
% of
IBase. The start forward or start reverse signals can be used in a communication scheme.
The appropriate signal must be configured to the communication scheme block.
