3.4.13 Summation block 3 phase 3PHSUM
3.4.13.1 Application
The analog summation block 3PHSUM function block is used in order to get the sum
of two sets of 3 phase analog signals (of the same type) for those IED functions that
might need it.
3.4.13.2 Setting guidelines
The summation block receives the three-phase signals from SMAI blocks. The
summation block has several settings.
SummationType: Summation type (Group 1 + Group 2, Group 1 - Group 2, Group 2 -
Group 1 or –(Group 1 + Group 2)).
