This setting specifies which current will be used by the P634 as the residual
current: either the calculated residual current derived from the sum of the phase
currents or the residual current measured at the fourth transformer.

For two ends of the transformer, the currents for each phase and the residual
currents can be combined. This setting specifies the transformer ends to be
involved.
