Operation principle

The source selector function is a multiplexer, where the output is selected from one of the eight input
phase group with a setting. It selects one of the analog input groups and forwards the selected input
group to the pre-processing component connected to its output. A group of transformer module
channels or merging unit channels can be connected to the source selector as the input source.

"INPUT1", the INPUT1 channel link strings are passed to the pre-processing component, and so
forth. Based on that link, the pre-procesing component fetches the data from the particular channel.
The IED supports four IEC 61850-9-2(LE) merging unit streams, wherein each stream has four sets
of current and voltage signals. In a hybrid configuration, the current and voltage can be either from a
conventional CT/VT (connection through TRM) or through the IEC 61850-9-2(LE) MU. The eight
input groups are provided per instance for the selection, out of which the last four input groups can
be connected to the merging unit signals, as there are diagnostic status signals that need to be
selected and provided as an output from the function.
