Lately the quality electrical system has begun to decline with frequent interruptions such as the breakdown of electricity to the load, unbalanced load, THD current exceeds the standard, the fuse on the incoming to the parent panel and the fuse on the main panel is often burned, the grounding system resistance value exceeds the standard equipment value, cable temperature exceeds the standard, even voltage rises to 500 volts. The purpose of this study is to determine the causes of disruption of electricity, and produce a new master installation design to improve the system. Based on the results of the analysis, it was found that the importance of channel separation between loads to the Dean building with the Departement of Architecture building with cable capacity for the Dean building of NYY 4 x 95 mm2 and the safety of the NFb 200 Ampere mains. For cables to the building load, the Departement of Architecture installed a new main cable with NYY 4 x 50 mm2 cable size and NFb 150A main safety. It is necessary to replace the main NFb safety at the MDP parent panel which supplies the load to the Departement of Mechanical Engineering building from 160 Ampere to 200 Ampere. The entire phase in each panel does not meet the IEEE 519 - 2014 standard, so it is very important to install a filter. Ground resistance values ??on all panels vary above the standard with a value of 12 to 62 ohms. So it needs to be made a new grounding. When using a plate grounding system, the number of plates that need to be planted is 25 sheets with a size of 2m x 1 m with a planting depth of 2 m. Whereas when using a grid type earth system, a grid with a size of 3 meters x 3 meters is needed with a total grid length of 2976 meters and a depth of 3 meters.

Abstract

AC (Air Conditioner), TV, lamp, LCD and others are categorized as nonlinear load generating harmonics. The high content of harmonics has a negative impact on the quality of electrical power. The result of measurement of THD (Total Harmonic Distortion) current at 9 ohm ground resistance value at phase R = 9,8%, phase S = 11,0%, phase T = 7,5% exceed from standard value IEEE 519 Year 2014 equal to ? 5 , 0%, THD measurement of phase voltage R = 1.4%, phase S = 1.2%, phase T = 1.3%, meet the maximum THDv standard of ? 5%. To overcome this problem, it was observed the effect of the value of ground resistance to THDi and THDv on the electrical system of the College of Engineering Faculty of Denpasar. This method of analysis with ETAP software simulation. With grounding system ? 3 ohm only effect on current THD only with decreasing value of THDi become: phasa R = 4,2%, phase S = 5% and phase T = 4,3%, meaning with grounding system ? 3 ohm THD current fulfill IEEE 519 - 2014 standard <5%. while THD voltage has no effect (THD value of fixed voltage). Several studies have suggested that THD repair can be done by filter installation. However in this study the installation of grounding system ? 3 ohms can reduce the value of current THD.
