APPLICATION OF CURRENT DIFFERENTIAL PROTECTION TO TAPPED TRANSMISSION LINES
1. Introduction
Microprocessor-based current differential relays offer superior protection for power transmission lines. The key advantages over distance relays include better sensitivity for high resistance faults, 100% line protection, and better performance in the single-pole-tripping mode, particularly during evolving and cross-country faults. Besides the well-known requirements of high-speed communication and sampling synchronization, a microp ....etc

Abstract
A new teleoperated system for live line maintenance is developed for electrical util-
ity. It's aim is to increase the safety and comfort of the workers and the overall
eciency, as well as to reduce labour requirements.Its design is basically like other
similar systems already developed. It consists of a pair of hydraulic driven master-
slave teleoperated manipulators placed on top of an insulated boom, which execute
directly on the hot line tasks commanded via master arms by an operator on the
ground. Tele-p ....etc

ABSTRACT
This is a new technique for the protection of transmission systems by
using the global positioning system (GPS) and fault generated
transients. In this scheme the relay contains a fault transient
detection system together with a communication unit, which is connected
to the power line through the high voltage coupling capacitors of the
CVT. Relays are installed at each bus bar in a transmission network.
These detect the fault generated high frequency voltage transient
signals and record the time ....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
