Expert Mode - AEMC PowerPad III 8336 User Manual

5.2.5 EXPERT MODE

The Expert mode is available with a 3-phase connection only. It displays the influence of the harmonics on heating
the neutral and on rotating machines. To display the expert mode press the ▲ or ▼ button. The selection is highlighted in
yellow and the screen simultaneously displays the expert mode.
From this screen, two sub-menus are available:
● V for 3-phase set-ups with neutral or U for the 3-phase set-up without neutral
● A for the expert mode in current
NOTE: The breakdown into sequences shown in the following figure is valid only in the case of a balanced load.
PHASE-TO-NEUTRAL VOLTAGE EXPERT MODE
For 3-phase set-ups with neutral, the V sub-menu displays the influence of the harmonics of the phase-to-neutral voltage
on the heating of the neutral and on rotating machines.
■ Column One: The harmonics inducing a negative sequence.
■ Column Two: Those inducing a zero sequence.
■ Column Three: Those inducing a positive sequence.
■ %: Level of harmonics with fundamental RMS value as reference (%f) or the (total) RMS value as reference (%r)
For 3-phase set-ups without neutral, the U sub-menu displays the influence of the harmonics of the phase-to-phase
voltage on the heating of revolving machines.
