An Improved Method for High Impedance Fault Detection in Medium Voltage Networks

Original scientific paper This paper presents a set of rules for an intelligent algorithm of high impedance fault detection by observing the phase to ground voltage, phase to phase current and harmonics of fault current. Several techniques to detect high impedance faults already exist for example current injection in the neutral, superposing voltage signals, harmonic analysis, neural networks. ...

A Novel Solution to Restricted Earth Fault Low Impedance Relay Maloperation

In this paper, various methods of providing restricted earth fault protection are discussed. The proper operation of high and low impedance Restricted Earth Fault (REF) protection for various applications has been discussed. The maloperation of a relay due to improper placement of CTs has been identified and a simple/unique solution has been proposed in this work with a case study. Moreover, it...

Low-Swing Voltage-Mode Driver Impedance Control

Transmitters are used to pass data stream through transmission lines in either current or voltage mode. In high data rate applications, the output impedance of transmitters should match the transmission lines’ characteristic impedance and should be tunable in order to compensate the process, voltage, and temperature variations. The multiplexing technique can be used to extend transmitters signa...

Improved Procedure for Screening Expression Libraries for Novel Autoantigens

The standard method for immunoscreening of a cDNA expression library is time-consuming becauseof the production of a large proportion of false positives during the first and second round of screening.This problem is more important when a sensitive chemiluminescence detection system is used. Due tothe high sensitivity of the detection system, there is a need to avoid false posi...

Fault Tolerant , Low Voltage SRAM Design

Scaling of process technologies has made power management a significant concern for circuit designers. Moreover, denser integration and shrinking geometries also have a negative impact on circuit reliability. Therefore, fault tolerance is becoming a more challenging problem. Static Random Access Memories (SRAMs) play a significant role in circuit power consumption and reliability of digital cir...
