The influence of multidirectional leakage flux on transformer core losses [PDF]

open access: yesJournal of Magnetism and Magnetic Materials, 2021
In a power transformer, the leakage flux enters the laminations of the iron core in different directions. Depending on the orientation of the leakage flux, it can add eddy current and hysteresis losses to the well-documented losses caused by the main ...

A study of magnetic flux-leakage signals

Journal of Physics D: Applied Physics, 1998
Magnetic flux-leakage (MFL) measurement is the most widely used non-destructive technique for in-service inspection of oil and gas pipelines. The effect of line-pressure-induced hoop stress on MFL signals has been studied for an electrochemically milled pit (50% penetration) in a 9 mm thick steel pipe wall.

Optimisation of the flux distribution in magnetic flux leakage testing

Insight - Non-Destructive Testing and Condition Monitoring, 2009
In the magnetic flux leakage (MFL) non-destructive testing technique there are many factors that cause degeneration of the measured signal. One of these factors is non-uniformity of the magnetic flux inside the sample under test. Uniformity of the magnetic flux results in smoother and more predictable signals from various flaw types and also a ...

Leakage flux in a single phase transformer

Journal of Magnetism and Magnetic Materials, 1984
Abstract The effects of aluminium magnetic shielding and mild steel magnetic shunts on the leakage flux in the steel tank of a single-phase 50 Hz low power transformer have been investigated.
