Dielectric strength of station and line insulation to switching surges

THE STRIDES achieved since the early thirties in the field of system-insulation rationalization are well known in recent technical literature^1–7 and need not be reviewed here. However, a point to emphasize is that further progress in this industry-wide problem can be attained only through continued research and studies directed particularly to the remaining major questions. In this manner it will be possible to pursue in future developments the principles of system-insulation rationalization to their fullest economic possibilities.
