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

The circuit presented here can beused for connecting two telephones in parallel and also as a2-line intercom.Usually a single telephone is connectedto a telephone line. If another telephoneis required at some distance, a parallelline is taken for connecting the othertelephone. In this simple parallel line operation,the main problem is loss of privacybesides interference from the otherphone. This problem is obviated in thecircuit presented here.Under normal condition, two telephones(telephone 1 and 2) can be usedas intercom while tel ....etc

A Current-Mirror Differential Amplifier


Prelab
The following prelab questions have been constructed to help you prepare to do the lab
efficiently. Unless otherwise stated, you should assume that like transistors are matched and
that the Early effect is negligible. Please complete these questions before you come to lab.
While you may discuss the prelab questions with your lab partner or with other students in
the class, each student in a lab group should c ....etc

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
