For the purposes of this document, the following tenns and definitions apply. The IEEE Standards Dictionary Online should be consulted for terms not defined in this clause.
acceptance test: A field test made after cable system installation, including terminations and joints, but before the cable system is placed in normal service. The test is intended to detect installation damage and to show any gross defects or errors in installation of other system components.
cross linked polyethylene (XLPE): A thermoset filled or unfilled polymer used as electrical insulation in cables. If filled, it is referred to as a filled XLPE.
diagnostic test: A field test made during the operating life of a cable system. It is intended to determine and, for some tests, locate degraded regions that may cause cable and accessory failure.
electrical trees: Tree-like growths, consisting of non-solid or carbonized micro-channels, that can occur at stress enhancements such as protrusions. contaminants, voids, or water trees subjected to electrical stress. The insulation is damaged irreversibly at the site of an electrical tree.
ethylene propylene rubber (EPR): A type of thermoset filled polymer used as electrical insulation in cables and accessories.
NOTE —There arc several different formulations of mineral-filled EPR and they have difTcrent charactcristics. For purposes here, the term also encompasses ethylene propylene diene monomer rubber (EPDM).
extruded dielectrics: Insulation such as PF., XLPE, TRXLPF.. F.PR, etc. applied using an extrusion process.
installation test: A fkld test conducted afler cable installation but bcftrc jointing (splicing) or terminating or energizing. The test is intended to detect shipping, storage, or installation damage. It should be noted that temporary terminations may need to be added to the cable to successfully complete this test, particularly for cables rated above 35 kV.
laminated dielectrics: Insulation fonned in layers typically from tapes of either cellulose paper or polypropylene or a combination of the two. Examples are the paper insulated lead covered (PILC) and mass-impregnated non-draining (MIND) cable designs.
maintenance test: A field test made during the operating life of a cable system. It is intended to detect deterioration and to check the serviceability of the system.
mass-impregnated non-draining (MIND): A cable design using impregnated paper insulation. The impregnating compound has a sufficiently high viscosity at maximum operating temperature to preclude migration or draining of compound.
monitored sithstand: A test in which a voltage of a predetermined magnitude is applied for a predetermined time. During the test other properties of the test object are monitored and these are used, together with the withstand results, to determine its condition.
paper insulated lead cosered (PIEC): A cable design using impregnated paper insulation. The paper tapes are applied unimpregnated, the complete insulation being subsequently dried and impregnated with a compound as a whole.
polyethylene (PE): A thermoplastic polymer used as electrical insulation in cables.
shielded cable: A cable in which an insulated conductor is enclosed in a conducting envelope.
simple withstand test: A test in which a voltage of a predetermined magnitude is applied for a predetermined time. If the test object survives, the test it is deemed to have passed the test. Svn: non- monitored ssithstand test.
tree retardant cross linked polyethylene (TRXIPK): A thermoset polymer used as electrical insulation in cables. It is based on XLPE and contains an additive, a polymer modification, or a filler that retards the development and growth of water trees in the insulation.IEEE 400-2 pdf free download.
