Increasing the Accuracy of Electrical Power Measurement

Mammadov Rahim, Genjeyev Namig

Correlation of direct measurement errors of voltage and current is ignored and assumed to be zero in the measurement of electrical power signals. Therefore, the accuracy of power measurement is obtained less than the accuracy of direct measurements. In this regard, increasing the power measurement accuracy is an urgent task by taking into account correlation of direct measurement errors. A certain methodology is proposed in the paper taking into account the correlation of direct measurement errors, which increases the accuracy of the power signal measurement.
