An Enhanced Avdonin‐Based Approach With Probabilistic Coefficients for Incipient Fault Modeling in Underground Power Cables

open access: yesInternational Transactions on Electrical Energy Systems, Volume 2025, Issue 1, 2025.
One well‐known fault that arises from water intrusion and power cable insulation failure is the incipient fault (IF) in underground power cables (UPCs). Therefore, it is necessary to provide appropriate models for modeling this fault and also to generate data close to the actual value for validating IF detection methods. This study presents a model for

Recent Advances in Design of Fault Current Limiters for Modern Power Grid Networks: A Critical Review

open access: yesJournal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
Fault current limiters (FCLs) are essential components in modern power systems for critical protection against the damaging effects of fault currents. With extensive short circuits, routine electrical faults, and an increasing risk of failure due to unprecedented events, the development of different types of FCL has gained attention.
