Electric power utilities throughout the world are undergoing considerable change in structure, operation, and regulation. One of the major effects of this change is increased importance of distribution automation. With improved Distribution Automation (DA), both the reliability and the efficiency of electric power distribution can be increased. Communication system is essential to performance of automated distribution systems. It is necessary to perform reliability assessments of communication facilities in carrying out the control functions. T ....etc

With the increasing loads, voltages and short-circuit duty of distribution substation feeders, distribution over current protection has become more important today than it was even 10 years ago.

The ability of the protective equipment to minimize damage when failures do occur and also to minimize service interruption time is demanded not only for economic reasons but also because the general public just expects ?reliable? service. This publication will attempt to review some of the present distribution practices, particularly with regard to ....etc

ABSTRACT
The hottest technology in personal networking is wireless networking, which allows users to share a high-speed internet connection among multiple computers without being tethered to wires or wall jacks. Traditional indoor wireless uses a network of transmitters receiver and antennas for communication in the interior of a building. Such a placements is more a matter of trial & error and may many a times lead to ineffective communication. An easy solution to this problem using the already existing infra ....etc

This paper is an overview of the sources and nature of various transient over voltages and the problems that may result in a low voltage ac distribution system. Voltage transients may be repeatable transients or random impulses and they have got remarkable effects on semiconductors, electrochemical contacts, insulation etc. Switching parallel loads on the same branch of distribution system as well as lighting are responsible for these transient overvoltages. Low voltage ac mains system should be protected from these transient overvoltages. For ....etc
