Review of Insulation Ageing and Lifecycle Management for Oil‐Immersed Power Equipment: From Conventional Testing Analysis to Artificial Intelligence Method

High Voltage, EarlyView.
ABSTRACT Oil‐immersed power equipment is a critical component for energy transmission and secure operation of modern power grids. The ageing of oil–paper insulation under combined electrical, thermal and mechanical stresses directly affects equipment lifetime and system reliability. This paper presents a comprehensive review of the ageing behaviour and

Islanding Detection in Power Distribution Systems Using a Hybrid Machine Learning Approach

Vector: The Journal of Engineering, Volume 2027, Issue 1, January/December 2027.
This paper proposes a hybrid islanding detection approach that combines passive monitoring of multiple electrical parameters—such as negative sequence voltage, generator field voltage, and the rate of change of positive sequence impedance—with intelligent machine learning techniques.
