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

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 procedur ....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
