description A device (10) for applying and measuring a transient overvoltage in an electrical cable includes a test specimen representative of the electrical cable, a first DC voltage generator (DC1) designed to apply a predetermined DC voltage to the specimen, and a second DC voltage generator (DC2) designed to apply a predetermined overvoltage to the specimen. The device also has a high-voltage switch (12) that is connected to the second DC voltage generator (DC2) and is designed to convert the predetermined overvoltage into a square-wave voltage, a control resistor (R2) designed to monitor the voltage rise time of the specimen, and a decoupling capacitor (C1) designed to monitor the overvoltage fall time in the specimen.
