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, ....etc

TRANSMISSION OF DATA OVER ELECTRIC POWER LINES



INTRODUCTION


aims at the utilization of the electricity power lines for the transmission of data
gains importance that every building is connected to the power grid that cannot be matched by either the telecommunications or cable TV wiring
provides new services to the users, which are difficult to implement by other technologies, e.g., remote electricity meter reading, broadband over internet and many

Abstract

This paper is focused on the development of the new principles and operational algorithms of the transmission lines distance protection. The proposed distance protection algorithms utilize statistical information about the undefined and random parameters and quantities such as equivalent impedances of the systems at the unmonitored end of the power transmission line and current and voltage phasor measurements errors. Knowledge about the distribution of these parameters and values results in more secure and dependable proce ....etc
