Thd (4V); Thd (4A) - AEMC PowerPad III 8336 User Manual

Item Function
1 Instantaneous value cursor; change values with the cursor using the ◄ and ► buttons
2
Harmonic distortion rate for each curve
Instantaneous value of the signals at the intersection of the cursor and the curves
t: time relative to the start of the period (expressed in milliseconds)
3
U1: instantaneous phase-to-phase voltage between phases 1 and 2 (U
U2: instantaneous phase-to-phase voltage between phases 2 and 3 (U
U3: instantaneous phase-to-phase voltage between phases 3 and 1 (U
