Functional diagrams for measurement functions

The phase current inputs to the relay are measured by the three-phase current
measurement function CMMXU1. The current input is connected to the X120 card in the
back panel. Similarly, the sequence current measurement CSMSQI1 measures the
sequence current and the residual current measurement RESCMMXU1 measures the
residual current.
The three-phase bus side phase voltage inputs to the relay are measured by three-phase
voltage measurement VMMXU1. The voltage input is connected to the X130 card in the
back panel. The sequence voltage measurement VSMSQI1 measures the sequence
voltage and the residual voltage measurement RESVMMXU1 measures the residual
voltage.
