Investigation of the effect of winding clamping structure on frequency response signature of 11 kV distribution transformer

This paper presents an investigation on the sensitivity of frequency response of a 500 kVA, 11/0.433 kV distribution transformer with and without the presence of a winding clamping structure. Frequency response analysis (FRA) measurements of multiple test configurations were carried out with and wit...
