Simultaneous Display - AEMC PowerPad III 8336 User Manual

5.3.5 SIMULTANEOUS DISPLAY

The sub-menu displays all the voltage and current measurements (RMS, DC, THD, CF, PST, PLT, FHL and FK).
NOTE: The display screen varies depending on which value is selected.
● 3U: Displays the RMS, DC, THD and CF values of the phase-to-phase voltages.
● 4V: Displays the RMS, DC, THD, CF, PST and PLT values of the phase-to-neutral voltages and of the neutral.
● 4A: Displays the RMS, DC, THD, CF, FHL and FK values of the phase and neutral currents.
● L1/L2/L3: Displays the RMS, DC, THD, CF, PST and PLT values of the phase-to-neutral voltage and of the
current, the DC and PST parameters of the phase-to-neutral voltage, and the DC value (if the current sensor
allows) and FK of the current for phase 1.
● N: This screen displays the RMS, THD and CF voltage and current of the neutral, the DC component of the
neutral voltage, and (if the current sensor allows) the DC component of the neutral current.
Item Function
RMS
True effective value of voltage or current
DC
Direct component
THD
Total harmonic distortion rate
CF
Peak factor calculated in relation to the displayed waveform
PST
Short-term flicker calculated over 10 minutes
PLT
Long-term flicker calculated over 2 hours
FHL
Harmonic loss factor for oversizing of transformers relative to harmonics
FK
K factor - Oversizing of transformers relative to harmonics
NOTE: The DC value of the current of phase 1 is displayed only if the associated current sensor can measure direct
current. L2 and L3 provide the simultaneous display of the current and voltage for phases 2 and 3, respectively.
