The Vivitron is a large electrostatic accelerator in operation under high voltage since December 1990. Since then, the machine sustained more than 750 sparks and operated 17 000 hours at voltages up to 20 MV. paper presents review of electric stresses applied on insulators that particular HV generator following operational experience last years. It discusses some most recent results related electrical stress characterization i.e. calculations data from bench, factory field tests.
