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

This article describes the effect of tower displacement of two parallel transmission lines on the magnetic field distribution. Here, two parallel lines with the same working voltage and having the same span and in which the use of artificial tower displacement is made is modeled.Parallel transmission lines with different span lengths and different voltages produce tower displacements naturally and this is also modeled. Additionally, the effects like the spacing between the parallel lines, phase conductors arrangements and the transmission line ....etc

Abstract:
This Project can be used in houses and offices in which more than one telephone is connected in parallel through a single telephone line Our project is used to connect a maximum of four telephones in parallel. When any one of the phone is lifted, all the other lines are disconnected from the telephone line. The above condition is also applicable when the telephone ring arrives only one telephone which is connected to the telephone line which is lifted first, while the other three lines are disconnected from the telephone line. ....etc

hi,
i was working on a project where we have two sets of telephone lines( one working and other stand by). when ever the primary line fails, the stand by is connected. I wanted to know can we do the change over between the two lines electronically without using mechanical relay. if possible then how?? ....etc
