Distribution systems fault analysis considering fault resistance estimation
International Journal of Electrical Power and Energy Systems, 2011 Abstract 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 analysis algorithm for unbalanced three-phase distribution systems that considers a fault resistance estimate.

Impact of fault resistance and fault distance on fault current reduction ratio of hybrid SFCL
International Transactions on Electrical Energy Systems, 2017 Summary Superconducting fault current limiters (SFCLs), as the novel power system devices, have attracted attentions in the last years. However, in order to achieve the maximum benefit from SFCLs, their interaction with power system should be comprehensively evaluated before equipping the power system with them.

Coordination of adaptive distance protection in transmission and wind farm collector lines under resistive fault conditions [PDF]
International Journal of Industrial Electronics, Control and Optimization, 2020 Distance relays calculate the path impedance between the fault point and the relay location by sampling the voltage and current at the relay location. By using the ratio of the impedance estimated by the relay to the impedance of the line where the relay

A TSV Test Method for Resistive Open Fault and Leakage Fault Coexisting [PDF]
IEEE Access, 2021 Large-size TSVs have larger parasitic capacitance, which leads to more resolution challenges. At the same time, due to the opposite fault effect of resistive open fault and leakage fault in the ring oscillator, the coexistence of two types of faults will cause serious test confusion. These problems significantly increase the difficulty in the TSV test.

The use of phase voltage modules to select the damaged phase in case of single-phase earth faults
Омский научный вестник, 2023 In case of short circuits, the selection of damaged phases always precedes the determination of the damage location. To select the damaged phase, filter selector of the damaged phase are widely used, using symmetrical components of phase currents.

Blinded Fault Resistant Exponentiation [PDF]
, 2006 As the core operation of many public key cryptosystems, group exponentiation is central to cryptography. Attacks on its implementation in embedded device setting is hence of great concern. Recently, implementations resisting both simple side-channel analysis and fault attacks were proposed.
