INFLUENCE OF HIGHER HARMONICS ON MEASUREMENT OF REACTIVE ENERGY IN ELECTRICAL NETWORKS
The effect of higher harmonics on the readings of counters, especially reactive energy, is revealed. Incorrectness of meter readings is connected, first of all, with the difference of the so-called "measuring" equations of counters sewn into microprocessors. The performed theoretical studies confirm a number of experimental data obtained under real load conditions. The article analyzes the readings of reactive energy meters from different manufacturers. On the basis of the analysis, a different approach is proposed for estimating costs due to the generation, transmission and consumption of reactive power in the presence of voltage and current distortions in the power supply system.
