Application Manual
The three-phase terminal side voltage inputs to the relay are measured by three-phase
voltage measurement VMMXU1 whereas the bus side voltage input to the relay is
measured by three-phase voltage measurement VMMXU2. In addition to phase
voltage, terminal side residual voltage is measured by residual voltage measurement
RESVMMXU1. The three-phase voltage inputs as well as residual voltages are
connected to the X130 card in the back panel. The sequence voltage measurement
VSMSQI1 measures the sequence 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 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.
