Abstract
There are various diagnostic methods to assess the mechanical integrity of power transformers which are one of the most substantial elements of the power network. Sweep Frequency Response Method (SFRM) enables us to analyze transformers in situation, detect faulty cases and if necessary, faults can be repaired. SFRM is an effective diagnostic tool for detection of winding movement and other mechanical faults which affects the power transformer impedance. Key advantages of SFRM compared to other diagnostics are its proven sensitivity towards variety of mechanical faults and a lesser dependency on previous reference measurements. In case studies, the details of SFRM and other tests performed during manufacturing and transportation stages are presented. Elaborative analyses and findings are discussed in detail

Tarama Frekans Cevap Metodu Kullanılarak Güç Transformatörlerindeki Çekirdek ve Sargı Yapısının Mekanik Bütünlüğünün Tespiti
Abstract
Elektrik şebekesinin en önemli elemanlarından biri olan güç transformatörünün mekanik bütünlüğünü değerlendirmek için çeşitli teşhis yöntemleri vardır. Tarama Frekans Cevap Metodu (TFCM) ile transformatörler yerinde analiz edilmekte ve arızalı durumlar tespit edilerek gerekirse yerinde yapılan müdahaleler ile giderilebilmektedir. TFCM transformatör empedansını etkileyen mekanik arızaların ve sargılarda oluşan kaymaların tespiti için etkili teşhis yöntemlerinden birisidir. Diğer arıza teşhis yöntemleri ile karşılaştırılan TFCM’nin üstün noktaları, önceki referans ölçümlerine bağımlılığının daha az olması ve mekanik arızaların çeşitliliğine yönelik kanıtlanmış duyarlılığının bulunmasıdır. Örnek çalışmalarda TFCM’nin ayrıntıları, üretim ve ulaşım aşamalarında gerçekleştirilen diğer testler sunulmuştur. Detaylı analiz ve bulgular ayrıntılı olarak ele alınmıştır.
