ppt for icing of power transmission line in wikipedia

Abstract

In communications and electronic engineering, a transmission line is a specialized cable or other structure designed to carry alternating current of radio frequency, that is, currents with a frequency high enough that their wave nature must be taken into account. Transmission lines are used for purposes such as connecting radio transmitters and receivers with their antennas, distributing cable television signals, trunklines routing calls between telephone switching centres, comput ....etc

ABSTRACT
Transmission lines are considered one of the major sources of magnetic field. In recent years great public concern has arisen because of reports on adverse health effects due to Magnetic fields. The rapid increase of electric energy utilization and ascending geographical growth in the Gulf Cooperation Council (GCC) region led to the reality that utilities need to upgrade and develop existing and new transmission and distribution lines which resulted in the transmission lines to become inside the urban areas. This project is directed ....etc

ICING OF POWER TRANSMISSION lines during winter storms are a persistent problem that causes outages and costs millions of dollars in repair expenses. High-frequency excitation at approximately 8-200 kHz has been proposed as a method to melt ice. The method works by a combination of two mechanisms. At these frequencies, ice is a lossy dielectric, causing heating directly in the ice. In addition skin effect causes current to flow only in a thin layer on the surface of the line, causing resistive losses and consequent heating.In this article, w ....etc

ADSS Cables on EHV, HV, MV Transmission Lines

The installation of fiber-optic cables on transmission towers that support EHV, HV, MV transmission lines provides an effective communications system on electric networks. Electric utilities have used fiber-optic cables for several years to provide a communications page link between neighboring substations or between substations and the control desk. It opens new perspectives for the future to create all optical Internet and other c ....etc

Abstract:
This paper deals with the application of artificial neural networks (ANNs) to fault detection and location in extra high voltage (EHV) transmission lines for high speed protection using terminal line data. The proposed neural fault detector and locator were trained using various sets of data available from a selected power network model and simulating different fault scenarios (fault types, fault locations, fault resistances and fault inception angles) and different power system data (source capacities, source voltages, source angles ....etc
