Current measurement
Figure. 4.7 - 45. Current measurement submenu.
Current measurement submenu includes various individual measurements for each phase or phase-to-
phase measurement.
The
Current measurement submenu has been divided into four sections: "Phase currents", "Residual
currents", "Sequence currents", and "Harmonics".
• "Phase currents" and "Residual currents" have been further divided into four subsections
("Per-unit currents", "Primary currents", "Secondary currents" and "Phase angle"), and they
display the RMS, TRMS and peak-to-peak values, amplitude and power THD values as well
as the angle of each measured component.
• "Sequence currents" has also been further divided into the four above-mentioned sections,
and it calculates the positive, negative and neutral sequence currents.
• "Harmonics" displays current harmonics up to the 31
st
harmonic for the three phase
current (IL1, IL2, IL3) as well as the two residual currents (I01, I02); each component can be
displayed as absolute or percentage values, and as primary or secondary amperages or in
per-unit values.
