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.

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 ...
