IEEE 400.1-2018

This guide presents the recommended practices and procedures for direct voltage acceptance and maintenance testing of shielded, laminated dielectric insulated power cable systems rated 5 kV to 500 kV used in ac transmission systems. It applies to all types of laminated power cable systems such as paper-insulated metallic-sheathed, high-pressure pipe-type, low-pressure gas-filled, and low and medium pressure self-contained liquid-filled cables that are intended for the transmission or distribution of electric power. The tabulated test levels assume that the cable systems have an effectively grounded neutral system or a grounded metallic shield.
