Trapping phenomena are essential features controlling the transport properties of insulating
materials. Depending on the energy depth, traps can either assist transport or lead to long …

The integration density of electronic systems is limited by the reliability of the integrated
circuits. To guarantee the overall performance, the integrated circuit reliability must be …

The continuing development of HVDC power transmission systems presents many problems
related to evaluation of the reliability of power system assets [1]-[5]. In this context the …

Polarisation and depolarisation current (PDC) measurement and analysis is one of the
popular tools for effective diagnosis of power transformer insulation. Normally, it is assumed …

The behavior of polar polymeric dielectrics at high electric fields is controlled by several
factors. Among them, dipolar polarization and trapping and de-trapping of space charge are …

Charges freed from shallow and deep traps affect different portions of the polarization and
depolarization current (PDC). Thus, leading to crossover of the two current profiles. As …

In this paper, polarization and depolarization current (PDC) measurement and quantum
chemical calculation (QCC) are performed to investigate the impact of nano-filler addition on …

Researches on the transformer oil‐based nanofluids to determine its suitability for replacing
the conventional liquid insulation has been consistently happening for more than a decade …

Epoxy titania nanocomposites were prepared under optimum process conditions through
shear mixing of titania nanoparticles in to epoxy resin, for its potential application as insulant …

Nonlinear conductivity composites have a broad application prospect in high voltage power
systems. But the high filling content will be harmful to the overall properties of composites …
