CMC 356 Reference Manual

Note:
For very small phase shifts (< 0,3 °) and small excitation (< 10 %), too
small integration time (< 1 s) or sampling rate 3.16 kHz, the sign of the
reactive power cannot definitely be determined.
The accuracy of the power measurement depends primarily on the
accuracy of the current clamp.
6.11.7 Harmonic Analysis
This operating mode is designed for measuring stationary signals (e.g., not
sinusoid shaped). The input signal is separated into fundamental and
harmonic waves (Fourier Analysis).
The following items are measured:
frequency of the fundamental wave
amplitude of the fundamental and harmonic waves
phase shifts between the fundamental and harmonic waves (also from
the different channels)
The input signals are captured. Finally, the calculation of the measurement
items is carried out. During this time, the input signal is not taken into
consideration.
