Influence of Led Bulbs on Electromagnetic Compatibility Parameters

The paper inhere describes a study of various types of LED bulbs which are connected to the low-voltage power distribution systems. In that relation, the relevant parameters of electromagnetic compatibility are presented. There have been presented graphically the current curves in the phase and the neutral conductors and their harmonic composition. The performed measurements' results show that LED bulbs and LED luminaires change the harmonic composition of the current curve, which results in increased power and energy losses.
