A new air gap flux‐based technique to detect loss of field in synchronous generators

IET Electric Power Applications, Volume 18, Issue 5, Page 543-555, May 2024.
A new technique is proposed for loss of field (LOF) detection in synchronous generators (SGs). The proposed scheme employs the variations of SG angular velocity and load angle to reach this goal, while the mentioned parameters are estimated through air gap flux estimation.

Analytical Modeling of Demagnetization Effects on Magnetic Flux Leakage Signals in Ferromagnetic Pipelines

Magnetochemistry
Magnetic flux leakage (MFL) testing is a widely used non-destructive method for detecting defects in ferromagnetic pipelines. However, demagnetizing fields in ferromagnetic materials can distort MFL signals, reducing detection accuracy.
