Abstract: In view of castor oil as non-toxicity and good di-electric properties which can be used as dielectric fluid inside transformer. Castor oil, a polar liquid dielectric of vegetables origin is studied. This paper presents a description of frequency domain dielectric response technique with the physical and mathematics background. The measurements were made using the L-C-R meter connected by co-axial cable and signal generator. Relative permittivity of castor oil was determined at frequency ranging from 25Hz to 150 KHz and temperature ranging from 270C to 1000C. The data obtained have been statistically analysed. It was observed that the real part of the relative complex permittivity was frequency independent. It also shows that there is a slight deviation between complex permeability of the oil sample and temperature increases compared with the result of typical transformer oil.
