Abstract
The current differential protection scheme isone of the most sensitive method for protection of transmissionlines. However, its sensitivity can be compromisedby distributed shunt capacitance of the line, presence of seriescapacitor, current transformer inaccuracies and communicationlatency as well as asymmetries in communication.This paper proposes a novel sensitive current differentialprotection scheme for transmission line protection. Ituses Global Positioning System (GPS) for time synchronizedmeasurements while fibre optic ....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


This paper presents a new technique for the protection of power transmission systems by using the Global Positioning System (GPS) and fault generated transients, the Integrated Positional Protection technique.A specially designed integrated positional protection relay, which contains a fault transient detection system together with a substation communication network, is connected to the power line.The relay detects the fault generated high frequency voltage transient ....etc
