Functional diagram for measurement functions

The neutral side and terminal side phase current inputs to the relay are measured by the
three-phase current measurement CMMXU1 and CMMXU2. The three-phase current
input is connected to the X120 card in the back panel. The neutral side sequence
current measurement is measured by CSMSQI1 and the residual current measurement
RESCMMXU1 measures the residual current.
