| Summary: | This paper investigates the dissolved gas analysis (DGA) of aged palm oil methyl ester (POME)-based nanofluids. Thermal stress is applied to nanofluids with various concentrations of TiO2 and MWCNT nanoparticles.
The experiments are conducted on a laboratory scale, with
the POME-based nanofluids thermally aged at 130 oC in the
absence of solid insulating materials. The study aims to
compare the gases generated in both nanofluids. Four
different diagnosis methods are employed: Rogers Ratio,
IEC Gas Ratio, Duval Triangle, and Duval Pentagon. The
experimental results reveal nearly identical gassing
behaviors between the two nanofluids after thermal ageing.
These findings contribute to expanding investigations into
transformer fault diagnosis, particularly in cases where
various natural ester oils, including POME-based nanofluids,
are used in power transformer. This helps diversify the
growing body of research on DGA for natural ester oils,
which has largely focused on commercially dominant types. |
