Abstract :
This paper presented an investigation of diversity factors for Light Emitting Diode Lamps (LEDs) which are used in residential and commercial applications as energy efficient lighting bulbs. It is done by performing experimental tests on various LED lamps available in the market. The current drawn by several LED lamps are first measured to investigate the electrical characteristics. These measurements provide current harmonic characteristic of individual lamps. Then various configurations of LEDs were connected to a laboratory scale feeder to analyze the diversity factors. The results show that LED bulbs produce considerable amount of harmonics. However, various combinations of LED lamps can damp harmonics penetration into the distribution system.
