For all four analogue input signals into this filter (i.e. three phases and the residual
quantity) the input samples from the TRM module which are coming at rate of 20
samples per fundamental system cycle are first stored. When enough samples are
available in the internal memory, the phasor values at set frequency defined by the
setting parameter
SetFrequency
are calculated. The following values are internally
available for each of the calculated phasors:
•
Magnitude
•
Phase angle
•
Exact frequency of the extracted signal
