Summation block 3 phase 3PHSUM

Introduction

Summation block 3 phase function 3PHSUM is used to get the sum of two sets of
three-phase analog signals (of the same type) for those IED functions that might
need it.

Principle of operation

Summation block 3 phase 3PHSUM receives the three-phase signals from Signal
matrix for analog inputs function (SMAI). In the same way, the BLOCK input will
reset all the outputs of the function to 0.
