Service values CVMMXU

Main menu/Measurement/Monitoring/ServiceValues(MMXU)/SVR
Displays up to three instances of CVMMXU with measured values for S, P, Q, PF, U,
I, ILead, ILag and F.

Current phasors CMMXU

Main menu/Measurement/Monitoring/CurrentPhasors(MMXU)/CP
All three phase currents and their phase angles are displayed here.

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 ground voltages and phase angles are displayed here.

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 A phase signal and the negative sequence current
should be zero.
