008 [Input Current R]
[Input Current S]
[Input Current T]
Displays the RMS value of the L1, L2, and L3 phase AC input current. Default:
Min/Max:
Units:
Read Only
0.0/6553.5 Amps
0.1 Amps
009 [I Imbalance]
Displays the current imbalance calculated between phases L1, L2, and L3.
The RMS current for each phase is calculated by summing the instantaneous current squared as sampled
at the PWM peak and valley, and then taking the square root of the sum every AC line cycle.
The imbalance is then evaluated every AC line cycle by first finding the largest, smallest, and average
phase current. Two equations are then used to calculate the value displayed:
Based_on_Largest = (Largest - Average) x 100 / Average
Based_on_Largest = (Largest - Average) x 100 / Average
The equation that gives the higher value is used for the display.
