abstract = {This paper proposes a model-based decision taking solution for electrical machines winding insulation robustness study. The solution is based on the Belief Function (BF) theory. It is processed in two main steps: a first one aims to learn Weibull model parameters from some labeled aging Partial Discharge Inception Voltage (PDIV) data. Then a second classification step separates some unlabeled PDIV data according to the learnt Weibull models. The classification results can give information on the robustness and the reliability of the Electrical Insulation System (EIS) under a thermal constraint.},

abstract = {In low-pressure environment, partial discharges (PDs) appear for lower voltages, shortening strongly the machines life times fed by PWM inverters. A new approach is proposed for designing AC motor windings free of PD at low pressure. The method consists of adding a thin resistive layer on the outer surface of the enameled wire used for winding the machine. Thereby, PDs occur only in critical zones, near the wire connections, rather than randomly in coils. Consequently, a coil design with a small additional quantity of varnish in critical zones can increase strongly the partial discharge inception voltage (PDIV). The paper proposes a theoretical analysis of the improvement based on Paschen's law for its application in non homogenous electrical fields.},

abstract = {High temperature machines are progressively showing their interest as more and more electrical engineering problems required them: air extractor fans for fire emergency equipment, aeronautical actuators. It is therefore needed to develop heat-resistant insulation to increase the reliability under high temperature. A proposed solution is the use of anodized aluminum strip which insulation is from the family of ceramics. Previous works determined the dielectric behavior of this strip under high temperature stress. This machine, whose coils will be wound with this strip, will be exposed to various surroundings conditions. The aim of this paper is to determine the dielectric behavior of this strip under climate conditions as varying humidity level and negative temperature. Partial Discharge Inception Voltage (PDIV) as well as Breakdown Voltage (BV) are studied. The results are correlated with the Paschen's law using humidity and temperature corrections.},

A proposed solution is the use of anodized aluminum strip which insulation is from the family of ceramics. This insulation layer has a good resistance to this range of temperature as its melting point is around 2000 °C. Microscopic observations of this strip revealed cracks of the alumina layer on the edge: coils made with this strip show a premature breakdown. The purpose of this paper is to determine the efficiency of boron oxide deposited on coil edges to improve breakdown voltage level.},
