Impulse strength of insulated-power-cable circuits

Abstract
Pursuant to a request of the cable working group, AIEE committee on power transmission and distribution, a co-ordinated study has been made on the impulse strength of insulated power cables having various types of insulation and their accessories. The data included not only all published information, but also much privately contributed information. On the basis of these data and some supplementary tests recently made, tabulations of safe withstand impulse voltages have been prepared. The information is also discussed with regard to its significance for practical applications from the standpoint of switching surges as well as from the standpoint of lightning impulses. Recommendations are given for standardizing impulse-test procedures.
