Design and Analysis of a Small Scale Generator for the Portable Power Pack

Jeong H.G., Jeong N.J., Kim K.C., Jeong H.G., Jeong N.J., Lee J-H., Korea Institute of Energy Research, KR

In this paper, a small linear reciprocating engine and generator are designed and tested for a portable power pack. If an engine is used solely to produce electrical power in a portable power pack, it [...]

Overview of Polymer Nanocomposites as Dielectrics and Electrical Insulation Materials for Large High Voltage Rotating Machines

Han J., Garrett R., Siemens Power Generation, US

Polymer nanocomposites are defined as polymers in which small amounts of nanometer size filers are homogeneously dispersed. In power industry, electrical insulating polymers usually incorporate inorganic fillers to achieve specific electrical, mechanical, thermal properties and [...]
