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.
