    Most power transformers in the electrical power industry are oil filled, and insulation failure occurs when the oil-paper insulation system weakens to the extent that it can no longer support the high voltage connected to it. Dissolved gas analysis is a widely used method to detect incipient faults in oil-filled power transformers. View full abstract»

    The combination of a dielectric solid (paper) and a dielectric liquid (mineral, vegetable, or silicone) is the most commonly used insulation system in power transformers because of the favorable dielectric properties of these insulations and the high heat capacity of the oil, which allows for cooling. It is known that temperature is the main parameter in determining the aging of these insulations ... View full abstract»

    As one step toward the future smart grid, condition monitoring is important to facilitate the reliability of grid asset operation and to save on maintenance cost [1]. Most failures of the power grid are caused by electrical insulation failure, and a key indicator of such electrical failure is the occurrence of partial discharge (PD). Therefore, one focus of condition monitoring is to detect PD, es... View full abstract»

  • Novel butt-lapped PET-mica tape turn insulation for high voltage motors

    Turn insulation for high voltage motor coils is normally a glass cloth-backed mica paper tape that is applied to the magnet wire according to specified fabrication methods [1]-[4]. In contrast to the main insulation, turn insulation is much thinner and more easily damaged during production because there are many processing steps. Hence, there is more attention paid to the protection of the turn in... View full abstract»

    Historically, line composite insulators have been used with success in relatively clean environments mainly due to the simplicity of handling and better pricing than ceramic insulators. Voltage upgrading and compact design of overhead lines are new typical nisch areas for composite insulators. Hydrophobicity is a key parameter of composite insulators providing insulation performance much higher th... View full abstract»
