Sparse Representation Based Dielectric Loss Angle Measurement
Precise measurement of dielectric loss angle is very important for electric capacity equipment in recent power systems. When signal-to-noise is low and fundamental frequency is fluctuating, aiming at the measuring error of dielectric loss angle based on some recent Fourier transform and wavelet transform harmonics analysis method, we propose a novel algorithm based on sparse representation, and...

15 صفحه اولAbsolute surface coverage measurement using a vibrational overtone.
Determination of absolute surface coverage with sub-monolayer sensitivity is demonstrated using evanescent-wave cavity ring-down spectroscopy (EW-CRDS) and conventional CRDS by employing conservation of the absolute integrated absorption intensity between gas and adsorbed phases. The first C-H stretching overtones of trichloroethylene (TCE), cis-dichloroethylene, and trans-dichloroethylene are ...
متن کاملPhase Angle Control in a Series Rlc Circuit Using an Electronically Switched Capacitor
In this article the principle of the switched capacitor in a series RLC circuit is presented. The classical methods for phase angle control are described, and a novel control method, where the capacitor is placed in the centre of a bidirectional H bridge switches. Using an electronic circuit simulation program, the representative voltage and current curves are obtained. The phase angle at vario...
متن کاملComparative Harmonic Loss Measurement of Grain Oriented and Non-oriented Magnetic Sheets Using a High Precision Single Sheet Tester
Abstract: Local flux may be distorted in many regions of core, although total flux is usually sinusoidal. When attempting to predict the loss distribution in materials operating under localized distorted flux conditions, which occur in machines and transformer cores, it is essential that proper account of the waveform be taken. Moreover for development of new magnetic materials and generation ...
