Abstract--This paper proposes a partial discharge analysis in
cylindrical insulators model for finding electrical parameters.
There are three types of electric insulator, namely liquid, solid
and gas insulator. The capacitance, dielectric loss factor (tan)
are found by measuring PD Pattern of each insulator. The power
dielectric loss (Pd) of each electric insulator also calculates by
using the result of partial discharge measurements. As we know
that the partial discharge technique can show the performance of
electric insulator. The experimental results of partial discharge
analysis show that the performance of three insulators. It can be
the primary data of high voltage equipments design in electrical
standard level.
