Coordination of Overcurrent Relay In Distribution System

open access: yesELEKTRIKA- Journal of Electrical Engineering, 2022
The overcurrent phenomena are a dangerous condition that can be occurred in the electrical system and equipment. The condition of the overcurrent will cause the short-circuited current flows through the system and affect the other distribution line. The purpose of this study is to investigate the coordination of the overcurrent relay in different types

Busbar Fault Direction Identification Using Sequences of Displacement Vectors

open access: yesEngineering Reports, Volume 8, Issue 2, February 2026.
In this paper, a novel busbar fault direction identification scheme is presented. The proposed scheme is based on sequences of displacement vectors. The proposed algorithm is fast and simple enough to be embedded in a differential relay to assist the percentage‐restraint differential algorithm.

The Split‐Station Architecture: Decoupling Transformation From Distribution via Medium‐Voltage Superconducting Virtual Bus Extensions

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper proposes the split‐station architecture, which uses high‐temperature superconducting (HTS) cables as ‘virtual bus extensions’ to decouple transformation from distribution in medium‐voltage systems. PYPOWER simulations validated against Project Hydra 13.8 kV specifications demonstrate that a 3‐km HTS link reduces voltage drop by 46 ...
