Statistical Analysis of Electrical and Mechanical Breakdown Stress for Insulation Performance in High Voltage Power Transformer
Original scientific paper In electrical power system, variety of solid, liquid and gaseous materials are used for insulation target to protect the incipient failure inside the high voltage power transformers. The insulation is practically ended when the insulation system has become fragile enough to flourish cracks under the electrical and mechanical stresses to which it is subjected. The elect...
متن کاملActive high voltage insulation
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. This accumulation results in a charge-induced electric field component which steers the field distribution within the system advantageously. At eq...
متن کاملHigh Frequency Characteristics of Medium Voltage XLPE Power Cables
The response of a cable can be used to analyze the variation of the material characteristics along its length. For diagnosis of possible ageing, it is necessary to know how cable design, material properties and cable insulation ageing affects the wave propagation. A cable model has therefore been worked out based upon the high frequency properties of the cable insulation and conductor systems. ...
متن کاملHeat Transfer through the Electrical Insulation of Nb3Sn cables
For the LHC upgrade projects, CERN will rely on the Nb3Sn technology to build high field dipole and quadrupole superconducting magnets. In the frame of this R&D program, cooling studies are carried out to determine the heat extraction from this new type of accelerator magnets and the relevant quench limits. In this paper we present and discuss experimental results of heat transfer through the e...
متن کاملHigh-Voltage Insulation Power Modules - SystemDesign and Qualification
One of the substantial causes of reliability deficiencies in soldered-base power modules is the soldering between the substrate and the base plate. This is owing to the surface area of this interface, which is very large in comparison to other soldered areas, and the large mismatches between the Coefficient of Thermal Expansion of the insulator and the base plate materials. But not all failures...
