ERROR CORRECTOR FOR THREE-PHASE, THREE-WIRE, TRANSFORMER-CONNECTED METERS

摘要

Usage: This invention relates to electrical engineering and can be used to improve the accuracy of measuring the power consumption. The aim of the invention is to increase power measurement accuracy by compensating for systematic errors voltage transformer supplying electricity meters. SUMMARY OF THE INVENTION: two introduced additional capacitor whose capacitance compensated negative sequence current transformer load voltage. The apparatus also includes a transformer voltage and load capacitors. 2 yl.
