<p align="justify">Non-linear and power electronic devices such as variable speed drive, UPS, converter, etc cause voltage and current distortion at several points in power system. At those points, voltage and current waveform consist not only fundamental component, but also several components whose frequencies are integer number multipliers of fundamental frequency. Those components are called harmonics. Increasing use of those devices increases the number of harmonics in power system network.<p align="justify"><p>Meanwhile, the increasing needs of electricity have caused increasing price of electric energy to maintain sufficient supply of the electricity. This situation pushes power suppliers to develop the way of measuring energy consumed by customer in order to get the most accurate measurement. One-way commonly used is by using electronic energy meter that calculate the real consumed energy. This meter samples voltage and current waveform on its terminals and it calculates not only fundamental, but also the harmonic components. Therefore, the energy measurement will be more accurate.<p align="justify"><p>This final project will analyze the effect of harmonics on load side to voltage and current waveform on source side and its effect to energy measurement by electronic energy meter. Furthermore, this final project will analyze the effect of energy meter sampling frequency to the value of measured energy. Analysis is done by modeling the power system and simulating the harmonics. The case study of this final project is an industry in West Java.<p align="justify"><p>From the simulation, it can be concluded that harmonics on the load side will mostly go to the source side. Harmonics make energy measured on the load side increase while energy measured on the source side remains unchanged. By using filter on the load side, energy measured both on load and source side increase. Also, sampling frequency affects energy measurement where the lower sampling rate, the lower measured energy.
