3.1 Defnitions For the purposes of this document, the following terms and defnitions apply. The IEEE Standards Dictionary Online should be consulted for terms not defned in this clause. 2 cable loop: See: test loop. cable system: Cables with installed accessories. Cable accessories are typically joints and terminations. There may be other types of accessories associated with a cable system (e.g., measuring devices or fxtures). These need only to be incorporated in the test objects to the extent that they are deemed to have an impact on the operational characteristics of the cable system (adapted from CIGRÉ Technical Brochure [TB] 496:2012, page 6, 1.5.1). compensation cable: Cable that serves for compensating the polarization and conduction currents of the measured cable subjected to space charge measurements with the thermal step method and has identical capacitance to the measured cable (for more details, see Annex B). compensation cable loop: Compensation cable arranged in a cable loop with two terminations. depolarization time: Time starting—after voltage removal—as soon as the cable conductor has been short- circuited and grounded. full-size cables: Cables of the same size, design, and rated voltage as the power cables installed in the feld. load cycle test: Part of the electrical type tests for dc extruded cable systems for power transmission at a rated voltage up to 550 kV (adapted from CIGRÉ TB 496:2012, page 19, 4.4.2). (Equivalent to the heating cycle voltage test after IEC 62067:2011, 12.2.4, for ac cables.) long-duration voltage test: Part of the prequalifcation test for dc extruded cable systems for power transmission at a rated voltage up to 550 kV (adapted from CIGRÉ TB 496:2012, page 14, 3.4). (Equivalent to the heating cycle voltage test after IEC 62067:2011, 13.2.4, for ac cables.) measured cable: Cable subjected to space charge measurements with the thermal step method where the thermal difuser is installed (for more details, see Annex B).
