Mechanism Analysis of Sympathetic Inrush in Traction Network Cascaded Transformers Based on Flux-Current Circuit Model

Energies, 2019
When electric multiple units (EMU) pass the neutral zone, the traction transformer may generate sympathetic inrush, which will cause a malfunction in the transformer differential protection.

Transient Response Analysis of Quasi‐Synchronization and Self‐Synchronization Grid‐Connection Processes for Nuclear Power (N + X) Emergency Diesel Generator Units

Engineering Reports, Volume 8, Issue 8, August 2026.
The upper portion condenses the five‐unit EDG arrangement into repeated diesel–governor and generator–AVR modules, distinguishing four operating units from one standby unit. Measured data and the equipment configuration jointly support a calibrated full‐system model, which then feeds two parallel research tracks covering self‐synchronization and quasi ...

An innovative harmonic‐based approach for inrush current detection in low‐loss transformers

IET Generation, Transmission & Distribution
Transformer inrush current occurs due to the saturation of magnetic core. The magnetic characteristic of the core directly affects the inrush current waveform. Second harmonic and higher‐order harmonics are present in the inrush harmonic spectrum.
