Given extremely high porosity, aerogels have demonstrated remarkable advantages in serving as thermal insulation and wave-transparent materials. Unfortunately, their practical applications are greatly confined by inherent fragility. The recent emergence of polymer presents an ideal platform for the development flexible aerogel films. However, additional cross-linking agents necessitated constructing a robust structure, complicating production process. Herein, we report film based on...
To optimize the dielectric properties of poly(m-phenylene isophthalamide) (PMIA), nanodiamond (ND) particles are incorporated as doping fillers. However, they often cause issues like uneven dispersion, filler aggregation, interfacial incompatibility, and...
Aramid papers, renowned for their exceptional mechanical properties, insulting capabilities, and thermal stability, are crucial next-generation electrical electronic devices. Among them, poly(m-phenylene isophthalamide) (PMIA) papers exhibit practical potential...
Tailoring the high anisotropic thermal conductivity of polymer dielectrics for enhanced high-temperature breakdown strength with potential capacitive energy storage.
Dissolved gas analysis (DGA) is one of the most effective methodologies used for transformer fault diagnosis. However, only adopted index, namely accuracy rate, not adequate reliability assessment diagnosis schemes. A new approach to evaluate DGA-based methods presented in this paper, which both rate and sensitivity are chosen as indexes. With 628 samples collected from all over China, a comparative done with regards seven prevailing methods. The results show that, same type do always render...
Dissolved gas analysis (DGA) is a prevailing methodology being widely used to detect incipient faults in power transformers. Although various methods have been developed interpret DGA results, they may sometimes fail diagnose precisely, especially when solid insulation deterioration involved. This study presents time series correlation technique, which the sampled data of dissolved gases transformer oil are considered as and scheme statistics adopted explore manipulate fault information....
Poly-(meta-phenylene isophthal-amide) (PMIA) has been considered as an ideal insulating medium due to its excellent thermal stability and insulative strength. However, the poor conductivity limits application in complex electro-thermal environments.
