Andrea Cavallini was born on
21/12/1963. On december 1990 he obtained the laurea degree in
electrical engineering from the University of Bologna. From 1991 to
1994 he was a PhD student in electrical engineering at the
Department of Electrical Engineering in the same University. He
obtained the PhD in 1995. From 1995 to 1998 he was researcher at
the Ferrara University. Since 1998 he is associate professor at the
University of Bologna. He teaches the courses of "Reliability and
Statistics for Electrical Systems", “Maintenance and Diagnostics of
Electrical Systems”.
Andrea Cavallini works in the research fields relevant to endurance
modeling and diagnostics of insulation systems. In particular, his
research activity is focused, on one side, on the physics of
partial discharge (PD) phenomena (physical/stochastic modeling of
PD phenomena, effect of waveshape, frequency, positions of defects
etc. on PD phenomena). On the other side, he is involved in
research concerning PD identification in different types of
apparatus (cables, rotating machines, transformers, GIS) with
different types of insulation systems (polymeric, epoxy/mica,
paper/oil, gas). PD source identification is carried out resorting
to artificial intelligence and sognal processing techniques.
Andrea Cavallini is the Italian representative in the SC D1
(Materials and Emerging Technologies) of the Cigrè and IEEE member.
He cooperated/cooperates with prof. Gian Carlo Montanari to the
development of standards and technical specifications: IEC 61934
TS, Electrical measurements of partial discharges during short
risetime repetitive voltage impulses (convener prof. G. C.
Montanari), IEC 60034-18-41 TS, Qualification and type tests for
Type I electrical insulation systems used in rotating electrical
machines when fed from voltage converters, IEC 60034-18-42 TS,
Qualification and acceptance tests for partial discharge resistant
electrical insulation systems (Type II) used in rotating electrical
machines when fed from voltage converters, IEC 60034-27 TS Offline
partial discharge measurements on the stator winding insulation of
rotating machines, IEC 60034 NP Online partial discharge
measurements on the stator winding insulation of rotating machines.
He is co-founder of the University spin-off TechImp
Spa.
