“…The characteristic time changes from 2000 to 4000 s, and it increases as the numbers enlarge. Also, in comparing Figures 23 with 24, it is obvious that the peak value of the negative pulse voltage is commonly larger than that of the positive pulse voltage, which probably means that the negative pulse voltage has higher corona discharge energy [28]. …”

Converter transformer is the extraordinarily vital apparatus in the high-voltage direct current (HVDC). Transformer oil and oil-impregnated paper are considered as the essential parts of converter transformer, which has suffered various complex electric fields such as AC/DC composite electric field and polarity reversal. The occurrence of discharge or insulation failure in oil-paper insulation system will threaten the safety of the entire grid. Hence, efforts should be focused on investigating the charge behavior and improving the property of dielectric.This chapter presents a study aimed at investigating the influence of different types of nanoparticles on thermal and dielectric properties along with the relation between them and the effects of switching overvoltage on the charge coupling behavior of oil-impregnated paper, and the surface charge behavior on double-layer oil-paper insulation under pulse voltage is investigated.

“…Surface potential decay experiments are widely used as it is an efficient method in the study of charge transport in polymers [9][10][11][12][13][14][15][16]. In these experiments a film of polymer is submitted to a discharge from a needle and the ions produced are placed on the surface of the film.…”

In order to study charge trapping and transport in polyimide, we have submitted samples of Kapton HN to corona charging and measured its surface potential decay with an electrostatic voltmeter. We propose a two terms mobility to explain the experimental data: a non dispersive contribution based on Toomer and Lewis model added to a dispersive process, which is associated with the disordered structure of the material. The non-dispersive model alone did not fit well to the data for short times, but our assumption makes the theoretical expresion fit succesfully to the experimental data. Some important parameters related to the charge transport properties of the material are determined and discussed.
