Functional diagrams for measurement functions
The phase current inputs to the merging unit are measured by the three-
phase current measurement function CMMXU1. Similarly, the sequence current
measurement CSMSQI1 measures the sequence current and the residual current
measurement RESCMMXU1 measures the residual current.
The phase voltage inputs to the merging unit are measured by the three-phase
voltage measurement function VMMXU1. The sequence voltage measurement
VSMSQI1 measures the sequence voltage.
The measurements can be seen from the WHMI and they are available under the
Measurement menu in the left navigation bar. Based on the settings, function
blocks can generate low alarm or warning and high alarm or warning signals for
the measured current values.
The frequency measurement of the power system FMMXU1 and the three-phase
power and energy measurement PEMMXU1 are also available.
