Example for use of GRP_OFF signal in FXDSIGN
The Restricted earth fault function (REFPDIF) can be used both for auto-
transformers and normal transformers.
When used for auto-transformers, information from both windings parts, together
with the neutral point current, needs to be available to the function. This means that
three inputs are needed.

Figure 66: REFPDIF function inputs for autotransformer application
For normal transformers only one winding and the neutral point is available. This
means that only two inputs are used. Since all group connections are mandatory to
be connected, the third input needs to be connected to something, which is the
GRP_OFF signal in FXDSIGN function block.
