The environmental matters fostered the power generation using renewable energies. This led, among the different possible solutions, to the diffusion of wind farms for wind power generation. Different types of sensors capable to detect the Partial discharges (PD) activity in the power generator and in the other electrical apparatuses installed...

The PRPDA (Phase Resolved Partial Discharges Acquisition) systems usually employ 8 bits mathrm A/mathrm D converters. Avoiding the converter saturation, it has been necessary, during the measurements, to set the reference voltage on the expected maximum PD signals magnitude. There is an amplitude threshold below which PD signals are not...

Nowadays the massive adoption of electronic converters to supply electrical motors leads to critical problems during the normal operation. In fact when the motors are supplied by electronic converters, the stator insulating system could be subjected to over voltages due to reflection and resonance phenomena. Frequently this over voltages exceed...
