Partial Discharges in Electrical Machines for the More Electrical Aircraft. Part III: Preventing Partial Discharges

In this paper, the results obtained from lab tests on twisted pairs subjected to different voltage waveforms and atmospheric conditions are used propose how modify IEC Std. 60034-18-41. The goal is make standard suitable for More Electrical Aircraft (MEA). show that it initially necessary screen out materials through simple tests. enhancement factors temperature can be modified consider reduced pressures temperatures using a model. aging factor considering sensitivity of partial discharge inception (PDIV) at low enamel thickness. Eventually, reference will made drive discussed in Part I series draw conclusions about likelihood random wound stator reduce by modifying either inverter or insulation.
