Large power generators, especially hydropower generators with a few hundred megawatts power and a few ten kV voltages, have high inertial power while operating, so they must not only withstand the operating torques and forces during operation, but al

The acoustic emission signals produced by discharges of a point-plane electrode on the surface (surface discharge) of different oil-impregnated aramid pressboards are detected by a 150 kHz acoustic emission sensor mounted on the outside of the experi

Partial discharge (PD) measurements are well-established under AC stress and their reproducibility is also quite good concerning partial discharge inception voltage (PDIV) and partial discharge extinction voltage (PDEV). Furthermore, correlation betw

The destructive characteristics of partial discharges (PD) to insulation material are well known. PD in AC and DC stress has different behavior and characteristics. In the case of AC stress, phase-resolved partial discharge (PRPD) patterns, can be us

When a Partial Discharge (PD) signal, which travels through a cross-bonded (CB) power cable system, reaches a CB joint, the signal not only continues its way on the defect phase but it also enters and propagates in the other faultless phases. For ana
