ON THE CONSTANT‐CURRENT ERROR IN SKIN RESISTANCE MEASUREMENT

Psychophysiology, 1965
ABSTRACTA substantial reduction in skin resistance (SR) is produced by a rise in induced voltage. This indicates that with a constant‐current circuit, variations in voltage can have a significant effect on the SR level. Therefore, SR levels obtained with a constant‐current and constant‐voltage circuits were compared for a group of Ss. The higher the SR

Compensation of Current Measurement Error for Current-Controlled PMSM Drives

IEEE Transactions on Industry Applications, 2012
Accurate measurement of phase current is crucial in a current-controlled permanent-magnet synchronous machine (PMSM) drive system. Current measurement error directly deteriorates torque control performance. This paper analyzes effects of the current measurement error on the phase current and the output voltage of the current controller.

Influence of Voltage and Current Samples Errors on the Reactive Power Measurement Error

2020 XXX International Scientific Symposium 'Metrology and Metrology Assurance (MMA), 2020
Currently, for reactive power measurement the digital measurement methods are applied both in time and in frequency domain. When determination of the voltage and current samples, the errors of the measurement channels exists that results to the reactive power measurement error.

GROSS ERROR IDENTIFICATION IN CURRENT MEASUREMENTS

Electric Machines & Power Systems, 1997
ABSTRACT This paper proposes a parity mismatch based gross error identification scheme for ampere magnitude measurements. In the parity mismatch method, the constant in a given system is calculated using the estimated state and the observed measurement. The gross error in the measurement then propagates through the calculation procedure and indicates a

Savings-investment and the Current Account: More Measurement Error than Identity

Journal of International Money and Finance, 2022
Abstract Econometric estimates of the determinants of current account (im)balances invariably start with the accounting ‘identity’ that the current account is equal to the difference between (national) savings and (national) investment. However, this accounting relationship does not hold in the official data.
