Structure and DC breakdown properties of polypropylene/elastomer blends

, 2023
Thermoplastic materials, such as polypropylene (PP), are highly favored for usage as high voltage cable insulation systems due to their high melting temperature and flexible mechanical and electrical characteristics. In this regard, PP has the capability

Failure mechanisms of polyimide and perfluoroalkoxy films under high frequency pulses [PDF]

, 2010
Breakdown behaviors of polyimide and perfluoroalkoxy high temperature films under unipolar and bipolar repetitive pulses are investigated. A bipolar 20kV, 20 kHz and fast dV/dt pulse generator has been designed and built to study the impact of pulse ...

Impulse-driven surface breakdown data : a Weibull statistical analysis [PDF]

, 2012
Surface breakdown of oil-immersed solids chosen to insulate high-voltage, pulsed-power systems is a problem that can lead to catastrophic failure. Statistical analysis of the breakdown voltages, or times, associated with such liquid-solid interfaces can ...

DC and AC Breakdown Behaviors of Polyethylene/ Silica Nanocomposites

, 2017
The breakdown characteristics of insulating materials depend on the materials’ resistance against voltage. In nanocomposites, it has been reported that the breakdown strength of the materials could be higher, or even lower, than their unfilled ...

DC allowable electric field strength for naphthenic‐based and paraffin‐based transformer oils

High Voltage
Currently, the design of transformers insulation predominantly depends on the allowable alternating current (AC) field values for insulating oil established by Weidmann in the 1980s, lacking the research under direct current (DC) voltage for converter ...
