THD_O_Uab＝0.6％；THD_O_Ubc＝0.6％；
THD_O_Uca＝0.6％；
Screen 4: Display the odd harmonic distortion ratio
of 3-phase current
"HIO" displayed at the left top corner of the screen.
Ia, Ib, Ic and In of odd THD is shown as fig 3.2.15:
THD_O_Ia＝0.5％；THD_O_Ib＝0.5％；
THD_O_Ic＝0.5％；THD_O_In＝0.5％；
Screen 5: Display the even harmonic distortion ratio of 3-phase voltage
"HUE" displayed at the left top corner of the screen denotes THD-U-E.
The screen display is similar to screen 3.
Screen 6: Display the even harmonic distortion ratio of 3-phase current
"HIE" displayed at the left top corner of the screen denotes
THD-I-E.
The screen display is similar to screen 4.
Screen 7: Display fundamental RMS of 3-phase voltage
"H-U" displayed at the left top corner of the screen denotes
harmonic voltage. The index is displayed at the bottom of the
screen, "01" denotes fundamental wave.
When the connection mode is set as 3-phase 4-wire system,
3-phase voltage Ua,Ub, Uc of fundamental value is shown in fig
3.2.16:
Ua_1＝220.1V；Ub_1＝220.0V；
Uc_1＝220.1V；
When the connection mode is set as 3-phase 3-wire system,
3-phase voltage Uab, Ubc, Uca of fundamental value is shown in
fig 3.2.17:
Uab_1＝220.1V；Ubc_1＝220.0V；
Uca_1＝220.1V.
