Evaluation and Mitigation of Voltage and Current Unbalance at MSTP Undip Jepara

Abstract Marine Science Techno Park (MSTP) Diponegoro University is a central for the application of technology and research in fisheries marine sector under auspices University. After measuring electrical power quality parameters, voltage current unbalance problem was found on each SDP MDP at MSTP Undip Jepara Building. The final project designed to mitigate with load equalization method phase using ETAP 12.6 software. According ANSI C84.1-1995 standard, maximum value 5% according IEEE 45-2002 3%. results show that can decrease unbalance, neutral already meets standards. Based evaluation existing conditions, decreased from 21.522% 0.419%, bus 0.280% 0.015%, 35.5 ampere 1 ampere.
