3.9.3.5 Functional diagrams for measurement functions
The phase current inputs to the IED are measured by the three-phase current
measurement function CMMXU1. The three-phase current input is connected to the
X131, X132 and X133 card in the back panel for three phases. The sequence current
measurement CSMSQI1 measures the sequence current and the residual current
measurement RESCMMXU1 measures the residual current. Residual current input is
connected to the X130 card in the back panel.
The three-phase bus side phase voltage inputs to the IED are measured by three-phase
voltage measurement VMMXU1. The three-phase current input is connected to the
X131, X132 and X133 card in the back panel for three phases. The sequence voltage
measurement VSMSQI1 measures the sequence voltage and the residual voltage
measurement RESVMMXU1 measures the residual voltage.
The measurements can be seen in the LHMI and they are available under the
measurement option in the menu selection. 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 FMMXU1 of the power system and the three-phase
power and energy measurement PEMMXU1 are available. Load profile record
LDPRLRC1 is included in the measurements sheet. LDPRLRC1 offers the ability to
observe the loading history of the corresponding feeder.
