Abstract

Method and corresponding computer program for determining a characteristic electric strength αE2 of a power cable (10) comprising an internal cylindrical electrode (11), an external cylindrical electrode (12), and an insulating layer (13) of electric insulating material (MI) interposed between said electrodes (11, 12), starting from breakdown tests with alternating voltage on a plurality of thin circular flat samples (100) of insulating material (MI).
