Condition monitoring and maintenance are essential for ensuring stable and reliable operation of facility transformer

reducing costs

and increasing expected life. Foam cannot be avoided within the power transformer which illustrates at least one of the principal roots of insulation deterioration. Due to the intricacy of the dynamics within the insulation system

involving bubble creation

migration

and accumulation

challenges arise in understanding these mechanisms. Consequently

the problems caused by bubble dynamics require further investigation. This paper provides a scientific review of issues related to bubble formation

migration

and dispersion and their electrical effects on power transformers. Various descriptions are given to high-light impact of the dynamics of the bubble within high voltage insulation fields

which covers bubble generation mechanism

and therefore

the quintessential influencing factors

state-of-the-art advances in multi-physics coupled modeling of bubble dynamics

etc. Moreover

pending issues on bubble control and mitigation are addressed

as well as recommendations for future investigations. Nonetheless

this paper contains a useful quotation guide for researchers within an equivalent field of research

which can motivate readers to explore scientific solutions to prevailing bottleneck problems.
