Abstract

The existing low voltage distribution systems have various single and three phase loads with dynamic characteristics. Voltage disturbance is one of the most important threats to power systems. There is need to ascertain the condition of distribution in the three phase power network. The voltage unbalance arising at the point of common coupling (PCC) due to a combination of unbalanced three-phase loads or phase to phase loads should be evaluated and analysed for the proper solution in the power system. This paper examines the state of the power quality within the distribution system with respect to unbalanced voltage and current. This study investigates the case of power quality in a power system to ascertain the extent of voltage unbalance in the system. Measurements were carried out with the aid of multimeter and clamp meter to determine voltages (line and phase) and currents in the two locations. The readings were taken at 2:00 pm daily for a period of one week in each location. The result shows that there is no voltage unbalanced in the load distribution at the two locations. The paper concludes by suggesting appropriate measures to prevent voltage unbalance in power network in the future.
