ABB rec670 User Manual

All three phase currents and their phase angles are displayed here.
6.5.3 Voltage phasors VMMXU/VNMMXU
Main menu/Measurements/Monitoring/VoltagePhasors(MMXU)/Phase -
Phase/VP
Phase to phase voltages and phase angles are displayed here.
Main menu/Measurement/Monitoring/VoltagePhasors(MMXU)/PhaseEarth/
VN
Phase to earth voltages and phase angles are displayed here.
6.5.4 Current sequence component CMSQI
Main menu/Measurements/Monitoring/CurrentSequenceComponents(MSQI)/
CSQ
The current sequence component under monitoring displays the positive (I1),
negative (I2) and zero sequence (I0) current values for a three phase line, both
magnitude and phase angle for each component are displayed. These indicate how
well balanced a system is. In an ideal balanced system the zero sequence current
should be zero, the positive sequence current should be equal to the current of each
phase with the same phase angle (relative to GPS) as the L1 phase signal and the
negative sequence current should be zero.
6.5.5 Voltage sequence component VMSQI
Main menu/Measurements/Monitoring/VoltageSequenceComponents(MSQI)/
VSQ
The Voltage sequence component displays the positive (U1), negative (U2) and
zero (U0) sequence components in the system, and includes the magnitude and
phase angle of each component.
6.6 View metering values
6.6.1 Pulse counter logic PCGGIO
Main menu/Measurements/Metering/PulseCounter(PCGGIO)/PC
The output data generated from the pulse counter function include data about the
status of the counter and counter values.
