The traceability of measurements performed to gauge information about the operation of electrical power systems under nonsinusoidal conditions is an important and live issue, usually neglected by the technical Standards. A generalized definition of the “composite error” is proposed in this paper as a meaningful index for the metrological characterization of voltage and current transducers in steady-state nonsinusoidal conditions. In this connection, the relationship among the composite error, the classical ratio and phase-angle errors and other parameters characterizing the waveforms of the transduced quantities are pointed out. Finally, problems involved in the measurement of the composite error in steady-state distorted conditions are dealt with and the results of some experimental work are presented.

Abstract: | The traceability of measurements performed to gauge information about the operation of electrical power systems under nonsinusoidal conditions is an important and live issue, usually neglected by the technical Standards. A generalized definition of the “composite error” is proposed in this paper as a meaningful index for the metrological characterization of voltage and current transducers in steady-state nonsinusoidal conditions. In this connection, the relationship among the composite error, the classical ratio and phase-angle errors and other parameters characterizing the waveforms of the transduced quantities are pointed out. Finally, problems involved in the measurement of the composite error in steady-state distorted conditions are dealt with and the results of some experimental work are presented. |
