Dielectric characterisation of Fe(3)P nanoparticles based ester oil

open access: yesIET Nanodielectrics, 2018
The insulation as the root source of failure and ageing assessor makes it a crucial point for any power equipment design. The transformer's insulation requires an efficient dielectric fluid that acts as an ideal electrical insulant and better thermal ...

Bubble migration characteristics in power transformer oil under coupled stresses of forced vibration and electrical field

open access: yesIET Science, Measurement & Technology, 2023
The stresses existing in power transformers lead to the generation of bubbles. They are the primary source that worsens and leads to insulation failure. Due to the complexity of bubble dynamics, it is challenging to figure out bubble mechanisms. However,
