WHAT ARE THE DFT AND RMS MEASURMENTS PRINCIPLE IN NUMERICAL
TECHNOLOGY OF POWER SYSTEM ?? WHICH IS BETTER IN WHICH
QUANTITY MEASURNMENT??
Answer / otto
RMS
The AC component is the effective mean value of the positive
and negative peak values.
RMS is used in applications where the effect of the DC
component must be taken
into account.
DFT
In the DFT mode, the fundamental frequency component of
the measured signal is numerically calculated from the
samples. In some applications, for example, it can be
difficult to accomplish sufficiently sensitive
settings and accurate operation of the low stage, which may
be due to a considerable amount of harmonics on the primary
side currents. In such a case, the operation can be based
solely on the fundamental frequency component of the
current. In addition, the DFT mode has slightly higher CT
requirements than the peakto-peak mode, if used with high
and instantaneous stages.
