This guide presents procedures and recommended test voltage values for acceptance and maintenance high-direct-voltage testing of shielded power cable systems. It applies to all types of shielded insulated power cable systems rated 5 kV and above and is intended primarily for the transmission or distribution of power. The tabulated test levels assume the usual effectively grounded neutral system or a grounded shield. Consideration may be given to modifying the test voltage levels as may be appropriate for overinsulated cables and accessories. This guide is not intended to apply to unshielded power cables, communication cables, control cables, and high frequency or other special purpose cables. It is recognized that the procedures and tests outlined here may be applied to cables outside this scope and that information of some value may there by be obtained.
