Abstract : power transformer is the most important
device for reliable electrical power system. While
working with it, many faults may occur in it.
Diagnosis of these faults can be done with lot of
techniques. Here in this paper we focus on
transformer fault detection technique by Sweep
Frequency Response Analysis (SFRA). The SFRA is
nothing but monitoring the change occur in the
transformer R-L-C network. SFRA measurement is
done by using sweep frequency of the range of 20 Hz.
to 20 MHz applied to transformer in healthy and
faulty conditions. SFRA gives the results in the form
of signature curve in both the cases. From that
signature curve we can conclude whether fault
occurred or not.
This paper presents simulation study of transformer
equivalent circuit of winding and winding
deformation by sweep frequency technique.
Keywords- Power transformer, winding deformation,
axial and radial deformation, sweep frequency,
signature curve, sweep frequency response analysis.
