Phase Distance Relaying With Fault Resistance Compensation for Unbalanced Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2011)
This letter presents an extension of an existing ground distance relay algorithm to include phase distance relays. The algorithm uses a fault resistance estimation process in the phase domain, improving efficiency in the ...
Distribution systems fault analysis considering fault resistance estimation
(ELSEVIER SCI LTD, 2011)
Fault resistance is a critical component of electric power systems operation due to its stochastic nature. If not considered, this parameter may interfere in fault analysis studies. This paper presents an iterative fault ...
The geometry of the active strike-slip El Tigre Fault, Precordillera of San Juan, Central–Western Argentina: integrating resistivity surveys with structural and geomorphological data
(Springer, 2013-03)
The geometry and related geomorphological features of the right-lateral strike-slip El Tigre Fault, one of the main morphostructural discontinuities in the Central– Western Precordillera of Argentina, were investigated. ...
Extended Fault-Location Formulation for Power Distribution Systems
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)
In this paper, an extended impedance-based fault-location formulation for generalized distribution systems is presented. The majority of distribution feeders are characterized by having several laterals, nonsymmetrical ...
Modeling and Experiment of the Current Limiting Performance of a Resistive Superconducting Fault Current Limiter in the Experimental System
(2015-09-08)
In this paper, a 220-V resistive superconducting fault current limiter (SFCL) prototype is built and tested under different prospective fault currents, which vary from 0.8 to 7.4 kA. A 2D superconductor model is integrated ...
Recovery Tests of an Hybrid Current Limiter Composed of a SFCL in Parallel to an Air-Core Power Reactor
(Springer, 2015-02-01)
The resistive-type superconducting fault current limiters (RSFCL) prototypes using YBCO-coated conductors have shown current limitation for medium voltage class applications for acting time up to 80 ms. By connecting an ...
Electrical and thermal characterization of YBCO coated conductors for resistive fault current limiter applications
(2015-06-01)
Electrical and thermal characteristics of Yttrium Barium Copper Oxide (YBCO) coated conductors (CCs) with different architectures, with and without stabilizer layers, in resistive fault current limiters (RSFCLs) have been ...

Fault Current Limiter Using YBCO Coated Conductor-The Limiting Factor and Its Recovery Time
(Institute of Electrical and Electronics Engineers (IEEE), 2009-06-01)
A fault current limiter (FCL) based on an arrangement of parallel connected high temperature superconducting tapes constituting a limiter element was designed and tested in 220 V line for a fault current peak between 1 kA ...
Test results of a superconducting fault current limiter using YBCO coated conductor
(Institute of Electrical and Electronics Engineers (IEEE), 2007-06-01)
A single-phase superconducting fault current limiter (SFCL) using a 0.9 m length of YBCO coated conductor (CC) tape was tested in 220 V-60 Hz line for fault current up to 1 kA, operating in 77 K. In this work are presented ...
