Abstract

Abstract : This paper will di scuss about impact of nonlinear load in residential costumer to harmonic distortion. Electricity consumer behaviour particularly in the household sector with the development of technology will evolve . Equipment used for everyday purposes continues to grow and has become a lifestyle . The modern life is becoming fabulous with the invention of new technology, so that many more electricity utilities are used by people and their houses in daily life. Nowadays, loads in the housing electricity utility do not only contain of linier loads, but also non - linier loads such as television, computer, microwave, fluorescent lamp and so on. The problem uses nonlinear load is create harmonic distortion. The harmonic distortion will reduce the life time of electrical equipmen t and inefficiency. The purpose of this research is to do modelling and prediction of harmonics level on housing electricity utility. The modelling and prediction of this research was using harmonic analysis with ETAP PowerStation version 4.0.0 C. This exp eriment was done in five houses as sample. The measurement was done on non - linier load and Kwh - meter in every house using Fluke 41B. The result of measurement on Kwh - meter on houses was compared in order to get the analysis result for VTHD, ITHD, power fac tor and frequency. The results research showed that VTHD, power factor (PF) and frequency on house are comply to the normal standard. VTHD result (maximum 5) is 1 . 1 – 3 . 6 . Beside those, ITHD on house also comfortable to due standard, but there are house es that did not comply into the appointed standard. The analysis result showed that energy saving lamp cause the biggest harmonics level. The level of harmonics in every house depends on how many electricity equipment used in it
