Current and voltage harmonics in high-rise prefabricated buildings

摘要

Connecting a growing number of appliances in homes increases, in particular, the share of non-linear devices. Their operation causes harmonic currents which lead to deformed performances, and result in voltage distortions. This work is a study on the magnitude and order of current and voltage harmonics which may occur in power distribution within common prefabricated buildings. The basis for this work is measurement that was carried out in a typical urban residential area. At the same time, harmonic voltage was measured, including the total coefficient of distortion and currents in neutral conductors. The result is a determination of the operability of the power distribution system in civil building construction, with regard to compliance with standards in force.
