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.
