A Promising Nano-Insulating-Oil for Industrial Application: Electrical Properties and Modification Mechanism [PDF]

Nanomaterials, 2019
Despite being discovered more than 20 years ago, nanofluids still cannot be used in the power industry. The fundamental reason is that nano-insulating oil has poor stability, and its electrical performance decreases under negative impulse voltage.
