Partial Discharge Pattern Analysis of Palm Oil for Optimized Transformer Insulation Applications

Abstract

Insulation of the transformer is the most
important thing to resist the flow of current.
Typical insulation of solid and the liquids are used
in the transformer to dissipate the heat energy and
provide the coolant service to the transformers. In
previous years, the mineral oils are used for this
purpose, and now a days those materials are
converted into the vegetable oils which can provide
the sufficient insulation to the transformers. In this
paper “partial discharge pattern analysis of palm oil
for optimized transformer insulation applications”,
the palm-based oils are used as a dielectric
material. The design procedures include the
rectangular ultra-wide band magnetic core Tesla
transformer, in which the coupling coefficient has
become the popular one, it can be obtained through
the elephant herding optimization algorithm being
this two update vectors are processed. The iteration
process can yield the optimal value which is
attained for the coupling ratio. At the load of the
transformer the electrical characteristics of “partial
discharge test” is carried out, in which the
excessive voltage beyond the threshold limit can
cause the breakdown. This can be prevented under
the test. The experimental results are carried out on
the MATLAB/SIMULINK. Finally the comparison
results are carried out over the recent papers which
are mentioned in the references. Those papers
obtained the less efficiency when compared with
our proposed approach.
