3.20.20.3 Functionality
The transformer data combiner function OLGAPC is intended for the voltage
regulator function OL5ATCC.
3.20.20.4 Operation principle
The function of OLGAPC is to collect data from a parallel transformer via GOOSE
communication. The TR_DAT output, which contains the combined input data, is
connected to the OL5ATCC function block.
