Investigations into the transformer inrush current problem [PDF]

open access: yes, 2018
A transformer being energised may draw a large transient current from the grid supply, resulting in a temporary voltage dip at the point of connection (POC) where customers are connected. The voltage dip is dependent upon the magnitude of the transformer

Nanoelectronic Detection of Opioids: Machine Learning‐Powered Screening With Carbon Nanotube Field‐Effect Transistor Sensor Array

open access: yesSmall, Volume 22, Issue 49, 1 September 2026.
A carbon nanotube field‐effect transistor (NTFET) sensor array is constructed to screen different opioids with machine learning models. Codeine, fentanyl, hydrocodone, and morphine are tested using the NTFET sensor array and classified with both conventional supervised learning models and deep learning models.

Contribution of inrush current to mechanical failure of power transformers windings

open access: yesHigh Voltage, 2019
This work presents a study regarding the contribution of inrush current to the occurrence of mechanical fatigue in windings of a power transformer and, consequently, the impact of that phenomenon on the equipment's lifetime. In order to perform the study,

Mitigation of magnetising inrush current in three-phase power transformer [PDF]

open access: yes, 2020
During energization of no-load transformers, a high and peaky current flow on the primary side which has rich second harmonics. This current is magnetising inrush current and it is generated when transformer core is driven deep into saturation.

Solid Particle‐Liquid Metal Mixtures for Robust High‐Current Interconnects in Stretchable Electronics and Soft Robotics

open access: yesAdvanced Materials Technologies, Volume 11, Issue 16, 21 August 2026.
Metallic microparticles dispersed in liquid metal interconnects mitigate electromigration‐induced failure by reconfiguring internal current density distributions. These fillers facilitate the growth of a robust, protective gallium oxide shell at elevated temperatures, shifting the failure threshold toward a thermal limit.
