International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.Transformer faults can cause power outages, equipment damage, and costly repairs, making early detection critical. Traditional diagnostic methods like dissolved gas analysis (DGA) and frequency response analysis (FRA) are useful, but they often struggle with noisy, overlapping signals, and varying operating conditions.

IET Energy Systems Integration, Volume 7, Issue 1, January/December 2025.ABSTRACT Investigation of power converters for use in industrial drive applications finds that these converters are used low reliable components. To overcome this issue, in this paper, advanced power converters (multi‐pulse AC–DC and multilevel DC–AC converter) are developed and implemented to feed vector‐controlled induction motor drive (VCIMD), which
