SOURCE FREQUENCY
is measured via software-implemented zero-crossing detection of an AC signal. The signal is either a
Clarke transformation of three-phase voltages or currents, auxiliary voltage, or ground current as per source configuration
(see the
SYSTEM SETUP
ÖØ
POWER SYSTEM
settings). The signal used for frequency estimation is low-pass filtered. The
final frequency measurement is passed through a validation filter that eliminates false readings due to signal distortions and
transients.

harmonics are measured for each source for the total harmonic distortion (THD) and 2nd to 25th harmonics per phase.
