“…Eddy current shielding is another flux rejection technique which is suitable for odd-shaped tanks. However, the disadvantage of this method is eddy current losses are produced within the shield itself and the repelled flux from the shield can cause overheating in nearby structural parts [12].…”

“…Stray losses occurred in the different parts of the transformer, such as core clamps, walls, and top-plates of the tank, etc., can be calculated easily using FEA [11,12,13]. Similarly, efficiencies of different shielding and shunting applications for losses caused by leakage fluxes were defined in [14,15,16]. In all these studies, one of the main drawbacks is to model the studied transformer and its components accurately.…”

“…Literatürde, transformatörlerin kazan kayıplarının hesaplanması, azaltılması ve çeşitli sayısal yöntemler ile analizi çalışmalarına yoğunlukla rastlanmaktadır. Bunun yanı sıra kaçak akıların nüve tutucu elemanlar [2] ve iletken bağlantılarının gerçekleştirildiği bağlantı kutuları *Sorumlu Yazar (Corresponding Author) e-posta : aytac@kocaeli.edu.tr [3] gibi yapısal elemanlar ile çoğunlukla kazan kapağı üzerine yerleştirilen buşinglerin bağlantı noktaları [4][5] gibi kısımlarda bölgesel olarak meydana getirdiği güç kayıpları da literatürde incelenmektedir. Kazan duvarlarında meydana gelen güç kayıpları transformatörün sargı akımları, bağıl kısa devre gerilimi, sargı yapısı, sargılar ile kazan duvarları arasındaki uzaklık gibi fiziksel ve elektriksel parametrelere ek olarak kazanın üretiminde kullanılan malzemenin elektromanyetik özelliklerine de bağlıdır.…”
