A Non-Invasive Methodology for Magnetic Characterization of Transformers and Reactors [PDF]
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2023 The lack of data is a hindrance to the experimental determination of magnetic cores characteristics. This work presents a non-invasive and field-applicable methodology for electromagnetic devices characterization.

Determination of transformer board creep parameters under high‐mechanical and thermal stresses
IET Science, Measurement & Technology, 2021 During operation of a transformer, all components inside the transformer begin to age and lose their performances due to various stresses. Among these components, transformer boards (TB) used between windings have an important role in terms of equipment ...
