The distribution feeder was one of the components of the power distribution system. Based on
the scheme of connection, the radial distribution feeder belonged to the simplest distribution
feeder that was used to ...
In the present era, power quality becomes the most important concern in electrical power
systems. This phenomenon has become an increasing concern to utilities and their
customers in the process of power delivery. ...
Through high voltage lines generating units are connected to load centers to form a power
system. The generated voltage steppes up before entering a transmission line, which
moves large amount of power over a long ...
In the 21st century, developing countries are still struggling with unreliable power
systems that are not smart and automated. Many researchers show that reliability of the
power system can be improved by using ...

Power has been and is the integral part of every walk of life in the modern human history. In the
event of power transmission to appliances, transformer plays key role. As with all, if not most,
electrical devices, ...
With the rapid evolution of the wireless technology feature and because the existing 4G
networks will be unable to satisfy the ambitious key requirements for future wireless
networks, it has strived to the development ...
The high bit rate of data is transmitted for longer distances by using Dense
wavelength division multiplexing. Dense wavelength division multiplexing is mainly
affected by the Stimulated Raman scattering effect ...
The continuous growth of load demand has risen the current drawn from the source,
voltage drop and power loss at distribution networks. In addition, the radial type
configuration of distribution systems with ...
Energy conservation and efficient usage are vital to the country’s development. Energy demand
is increasing globally due to the depletion of fossil fuel sources and other related issues.
Significant results can be ...
Power system is a large system which is very sensitive to damage and failure especially during
transmission line and power generating unit outage that is why contingency analysis is
performed to investigate the power ...
