Power quality analysis of energy efficient residential load

Continuous and rapid growth of nonlinear load increases the harmonics in power system. The harmonics of energy efficient loads are not discussed much on the performance of the devices in terms of power quality, during the operating condition. These harmonics can cause excessive heat in many appliances, and hence reduce the life span. This paper studies the harmonic impact of different energy efficient residential load. The total harmonics distortion (THD) of each load has been measured.
