  • Abstract
    Experiments have been carried out to investigate the breakdown mechanism in Perspex over a temperature range from 20 to 160°C, using impulse voltages of widely differing rise times. The electric strength was found to be sensitive to voltage rise time, reaching a maximum as the rise time is increased, but falling again at longer rise times towards the dc value. The results are discussed in terms of a model in which space charges accumulate at the electrodes, positive charges at the anode, and negative charges at the cathode.
