Active high voltage insulation

Journal of Electrostatics, 2002
This paper presents a new concept for an active high voltage insulation system with dynamic and adaptive features. The governing principle is based on surface charge accumulation on dielectrically covered electrodes in air under atmospheric pressure.

Porcelain for High Voltage Insulators

Transactions of the American Institute of Electrical Engineers, 1936
In this paper the mechanical failure of porcelain is discussed with special reference to 3 seldom recognized characteristics: the effect of the porcelain surface on the strength, the apparent anomalous distribution of individual mechanical test values, and the effect of time on mechanical strength.

High Voltage Insulation Systems

2020
This chapter discusses insulation system design for the HG windings suitable for a 38.1 kV RMS phase voltage machine. The machine initial phase 6.35 kV voltage is scaled in steps to obtain the targeted 38.1 kV and appropriate winding insulations for each design step is considered.

Pulsed high-voltage insulation experiments

2014 IEEE 41st International Conference on Plasma Sciences (ICOPS) held with 2014 IEEE International Conference on High-Power Particle Beams (BEAMS), 2014
It has been conjectured that vacuum dielectric surface flashover can be avoided by preventing its initiation1. Assuming that the flashover process is initiated by impact of charged particles on the insulator surface, by deflecting these particles away from the surface, the development of a flashover avalanche can be repressed.

Insulation for High Voltage Equipment

2021
The insulation of high voltage apparatus is distinguished between internal and external insulation. The internal insulation is made fluid, gaseous or solid material. Beside the well-known insulation with oil-paper, SF6, or cast resin there are also new trends discussed. As external insulation porcelain as well as composite insultors are described.

High voltage generator insulation

1963 EI Electrical Insulation Conference Materials and Application, 1963
The insulation of high voltage stator windings for electric utility generators must have a very high order of reliability. Machines of this category have always been of extreme importance because of their size with the accompanying high capital investment and the dependence of so many things in our society upon their continuous and uninterrupted ...

Insulation characteristics of high-voltage cables

Proceedings of the American Institute of Electrical Engineers, 1917
The insulation characteristics of different types of single- and three-conductor cable, determined largely by dielectric energy loss measurements, are discussed in detail. Particular attention is given to paper insulated cable, both new cable and cable that has been in service being considered.
