Investigation on enhancing breakdown voltages of transformer oil nanofluids using multi‐nanoparticles technique

Abstract

This study presents particularly an innovative technique to enhance charging dynamics in transformer's oil using multi-nanoparticles (NPs). A charging dynamic process in power transformer oils is the main way to slow down the streamer propagation and upping dielectric strength. In addition, transformer oil's based suspension multi-NPs (dielectric, conductive, and semi-conductive) have substantial levels of deposited electrons higher than suspension traditional nanofluids. An experimental work has been done to verify the importance of using multi-NPs for slowing down positive streamer propagation in transformer oils against using individual NP techniques or traditional transformer oils.
