For distribution cable networks with voltage (6-10) kV, according to the above-mentioned Table 35.5 of [1], the time constant of the decay of the aperiodic component of the SC current takes the numerical value [T.sub.a][approximately equal to] 10 ms.
Small errors of Rogowski coils, absence of saturation in the modes of great primary currents, and in case of existence of the aperiodic component, linearity of amplitude-frequency, and phase-frequency characteristics allow finding the exact current derivative value and displaying its leading edge without distortion.
The system of the viscoelastic DE also presents stability transition from an aperiodic motion to the quasiperiodic motion for a relative high frequency and experiences a stability evolution from single cycle motion to multicycle motion with the increasing relaxation times for a fixed frequency.
The sensor without compensation, the sensor of compensation for periodic error, and the sensor of compensation periodic error and aperiodic error are installed in the experimental pipeline.
Harmonicity or Harmonics-to-Noise Ratio (HNR) measures the relative dominance of periodic to aperiodic ("noise") components of the voice (see Boersma; Wayland and Jongman).
