Abstract
We present the computational fitting program for the microhertz to terahertz
frequency dielectric data using different dielectric models. Dielectric spectroscopy
is the precise measurement of a material's electrical characteristics by logging the
correlation between current and voltage for a series of electrodes having the
material of interest. The experimental data are analyzed using Different dielectric
models (Debye, Cole-Cole, Cole-Devidson, Havriliak-Negami and Lorentz
oscillatory model in the frequency range of 8 x10 8 Hz to 2 x10 10 Hz and 1.1 x10 11
Hz to 1.5 x10 12 Hz. Python/Scilab is used to develop the programming to analyze
the Experimental data.
Description
Dielectric spectroscopy measures medium dielectric properties as a function of
frequency[1,2]. Dielectric spectroscopy enables us to differentiate between
different polarization methods. It also studied how faster and slower polarization
methods. Dielectric properties depend on many factors, e.g. in frequency, time,
temperature, the chemical composition of each dielectric, or in the structure of a
separation system composed of the different dielectric. Many of the above factors
are measured and analysed using standard tests but performed only with the
frequency of energy. The values above in one frequency are not sufficient to detect
changes in the dielectric properties of objects. Therefore, Dielectric Spectroscopy
are used. Now discuss about the need for dielectric spectroscopy. The most serious
deterioration is caused by the aging effects of the HV integration systems used
within the HV components. It is traditionally avoided to avoid any damage to the
timely care machine used naturally expensive. There is now a movement towards
condition-based care that reduces maintenance costs and extends the life of the
equipment. In CBM, real estate conditions should be known. To determine the
actual conditions, dielectric spectroscopy is used as a powerful tool.
