Abstract :
Preventive diagnosis and maintenance of transformers have become more and more popular in recent times in order to improve the reliability of electric power systems. Dielectric testing techniques such as frequency domain spectroscopy (FDS) are being investigated as potential tools for condition assessment of transformer insulation. The FDS test has been affected by the factors, such as, the geometric, temperature, moisture content of insulation system. In this paper, those effect factors will be analyzed, according the field test data and laboratory model data.
