Current direction adjustment
The right current direction is from port 1 to port 2. To adjust polarity of
current, the three currents direction can be set as “Negative” which means
reversing 180 degrees and “Positive” which means normal.
Sequence component and unbalance analysis
The DPMS XPQ will do some sequential analysis for the input signal. it
makes out the positive sequence, negative sequence and zero sequence of the
fundamentals and will do the unbalance analysis of voltage and current.
The following gure shows a sequence chart:
