Impact of Cable Impedance on the Harmonic Emission of LED Lamps

摘要

This paper presents the effect of installation cables on the current harmonics emission due to nonlinear loads. Climate change and volatile fuel prices are persuading policy-making institutions to move in the direction of energy efficiency practices. The energy-efficient models of household appliances contain power electronic circuits and, thus, a source of current harmonics. In order to estimate the influence of current harmonics on the distribution network, an accurate assessment of power quality is required when the non-linear sources are connected to the distribution grid. However, accurate assessment is a challenging task because of the involvement of various uncertainties. This paper focuses on the influence of installation cables on the current harmonics connected with the nonlinear devices.
