Abstract

The nanofluids are considered as next generation insulating fluids for the transformer application. In this work, synthetic ester, MIDEL 7131 based nanofluids were prepared under ultrasonication by employing nanoceramics such as Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT), Calcium Ferrite (CaFeO3) and eggshell nanomaterials. These nanofluids were evaluated for parameters such as AC breakdown voltage, loss tangent and resistivity, and also for viscosity and total acidity. There is an improvement in A C breakdown voltage for all the nanofluids under the study. There is no variation in the viscosity and total acidity for the nanofluids upto 0.005 wt percent of nanoceramic in a base oil. These nanofluids exhibited improved critical parameters.
