Note: Total Harmonic Distortion (THD) can be distinguished as THDF (for "fundamental"), and THDR (for
"Root Mean Square"). THDR cannot exceed 100%. At low distortion levels, the difference between the two
calculation methods is negligible. For instance, a signal with THDF of 10% has a very similar THDR of 9.95%.
However, at higher distortion levels the discrepancy becomes large. For instance, a signal with THDF 266%
has a THDR of 94%.

Power Factor Limits: APFC-06 has one set point for Mains.
Upper & Lower limits can be defined as Upper PF and
Lower PF. PF limits can be set as inductive or capacitive.
Freq 50 or 60 Hz: User can select supply frequency 50 Hz
or 60 Hz according to measurement (feedback) supply.
The Over / Under Frequency limits are automatic.
CT Polarity:
accordingly Active Power Sign is changed. If it is enabled,
APFC controller work in two-quadrant mode, by way of
internally considering Active Power (kW) as always
"Positive". Disabled Mode is for four-quadrant mode where
sign of kW can be +Ve or -Ve.
