Abstract
Changing incandescent lamps and Compact Fluorescent lamps (CFL) to light emitting diodes (LED) is one of the ways in enhancing energy efficiency in a building. LED lamps consume less power, longer lifespan and are environmental friendly because it is recyclable and does not contain mercury. However, LED lamps like CFL lamps create power quality (PQ) problem. LED lamps using electronic driver intended for changing AC to DC supply, switching and shifting of the driver can cause harmonic distortion for the connected system. Connecting a massive number of LED lamps can cause problems to the grid with the generated harmonic. This paper analyses the harmonic behavior for different branded of LED lamps based on IEC 61000-3-2 standard. Simulation of LED lamps will carry out by PSCAD/EMTDC software. Good quality LED lamps will produce lower harmonic distortion and the prices are also reasonable, so it can be high economical for the consumer. Thus, cost-effective of using LED lamps will be included in this paper.
