Measurement of Voltage, Current and Power at Distorted Waveforms

IEEE Instrumentation & Measurement Magazine, 2021
Electric power systems have been designed to operate under sinusoidal voltage and current conditions at power frequencies, mainly 50 Hz and 60 Hz, and by far most electrical energy transmission occurs at 50 Hz and 60 Hz. Electric utilities are responsible for providing a sinusoidal voltage to their residential, commercial and industrial customers.

Cochlear Distortion: Effect of Direct-Current Polarization

Science, 1969
Intermodulation components (combination tones) appearing in microphonic potentials were measured from guinea pig cochleas with and without polarizing direct currents passing through the cochlear partition. At moderate intensities of stimulus the polarization had a qualitatively different effect on the distortion components than on their eliciting ...

Characterization of Current Transformers in the Presence of Harmonic Distortion

2008 IEEE Instrumentation and Measurement Technology Conference, 2008
The CTs performance under distorted conditions are usually characterized by means of the frequency response test. In this paper a new way to characterize CTs, closer to real operative conditions, is proposed. The harmonic phase angle and ratio errors are measured when the CTs are excited with a nonsinusoidal current composed of a fundamental and one ...

Intermodulation distortion in current-commutating CMOS mixers

IEEE Journal of Solid-State Circuits, 2000
The nonlinearity behavior of CMOS current-switching mixers is investigated. By treating the mixer as a periodically-time-varying weakly nonlinear circuit, we study the distortion-causing mechanisms and we predict the mixer distortion performance. Normalized graphs are provided from which the designer can readily estimate the mixer nonlinearity for ...

The Measurement of Distortion Current and Distortion Power

IEEE Transactions on Instrumentation and Measurement, 1984
A converter for resolving current or voltage into three mutually orthogonal components-active, reactive, and distortion-is suggested. The described system confirms the possibility of measuring the distortion current and distortion power on the basis of the time-domain approach.

Distortion analysis of switched-current circuits

ISCAS '98. Proceedings of the 1998 IEEE International Symposium on Circuits and Systems (Cat. No.98CH36187), 2002
A distortion analysis based on the large signal behavior of the basic switched-current memory cell is presented. In the first part, based on a closed form solution of the step response, distortion due to the settling error is addressed. In the second part, distortion caused by clock-feedthrough is analysed. The solutions are compared with simulated and/

Influence of harmonic distortion in current transformer

2016 17th International Conference on Harmonics and Quality of Power (ICHQP), 2016
This study aims to evaluate the performance (accuracy assessment) of current transformers in the presence of harmonic distortion. Using the software ATP-Alternative Transients Program, an equivalent CT circuit model was validated and the simulation results were compared with tests performed in prototypes.
