A power transformer will yield a frequency response which is unique to its mechanical
geometry and electrical properties. Changes in the frequency response of a transformer can …

Any deformation or displacement in the transformer winding can cause change in the circuit
parameters and frequency response. The changes can be detected using Sweep Frequency …

Phase-shifting transformers for variable frequency drives (VFDs) are usually specialty
designed, and their applications become more common in oil field facilities. The frequency …

The wideband frequency response of a power transformer will yield a signature unique to its
mechanical geometry. A change in the frequency response can be indicative of winding …

Modelling of transformers began at the start of the twentieth century. Abetti [9] suggests that
the origins of transformer modelling can be traced back to a 1902 paper by Thomas [113]. In …

Power transformers are a vital link in electrical transmission and distribution networks.
Monitoring and diagnostic techniques are essential to decrease maintenance and improve …

Transformer is an important element of the power system. It has several applications in the
industry. For example, it is used to change the voltages from one level to another level and it …
