Electrical power system consists of vast and complex network of transmission and distribution power
lines. Transmission systems are managed by huge substations and are largely stable and operate
within the limits. Distribution systems, on the other hand, are largely complex and are often pushed
to the limits of its operation (operating voltages and currents). There is no ecient methodology for
monitoring the large electrical distribution systems which are often exposed to faults, disturbances
and interruptions. Along with ecient monitoring, an in-depth analysis of the behavior of the
distribution systems is needed to design a more robust and ecient power system. The upcoming
smart grid technology is a promising one to make the power systems more robust and ecient
with the distributed energy sources supplying power to the grid. In this work, an ecient power
monitoring system based on the wireless sensor network technology is proposed to enhance the
functioning of large distribution systems
