16、onductors in service are subjected to voltage surges from lightning, switching, and other sources.These surges vary widely in wave shape, magnitude, and frequency of occurrence. Laboratory tests cannotduplicate the wide variety of surges met in service. Standard test procedures, however, make it pos

17、sible tocompare the impulse strength of different insulations measured by different laboratories, at different times.1.1 ScopeThis test procedure applies to both switching impulse and lightning impulse tests on cables or cable systemsincorporating laminated or extruded insulations. The term laminate

18、d cable, as used in this procedure,includes high-pressure pipe cable, low-pressure gas-filled cable, self-contained liquid-filled cable, solid-paper cable, and other taped cable designs. A cable system is a cable with one or more accessories attached.This test procedure is not intended to replace an

19、y existing or future standards covering cable or cable acces-sories, impulse generators, impulse testing, or voltage measurements. It is intended to supplement such stan-dards by indicating specific procedures for a specific type of cable system or cable system component.This test procedure does not

20、 apply to cables or cable systems that utilize gas or gas spacers as the sole insu-lating medium. This test procedure applies to individual cable accessories only when referenced by the spe-cific accessory standard.1.2 PurposeThis test procedure is intended as a guide for impulse testing of insulate

21、d conductors (cables) and cableswith accessories installed (cable systems). It can be used as a design or qualification test for cables or cablesystems.2.

Specimen4.1 LengthA minimum cable length of 9 m between grounded ends of the test terminations, when no other accessoriesare involved or as required by the

30、specific cable standard, shall be provided. When other accessories areincluded in the test circuit, a minimum cable test length of 4.5 m between the ends of accessories, andbetween the accessories and grounded end of the test terminations, shall be provided. When testing accesso-ries only, shorter c

31、able lengths are allowed (see specific accessory standard).4.2 Electrode arrangement4.2.1 Inner electrode The inner electrode consists of the cable conductor, including any conductive shielding.4.2.2 Outer electrodeThe outer grounded electrode depends upon the type of cable and voltage rating.a) Shi

32、elded cables. Shielded cables, including those having external metallic coverings, shall be testedin their final construction, or as agreed upon between user and manufacturer.1) Pressurized cables and cable systems shall be tested at minimum recommended operating pres-sure, and with the design filli

33、ng medium, or as agreed between user and manufacturer.2) Other shielded cables shall be tested in air, at atmospheric pressure.3) Other specifications may require certain extruded cables to be tested in conduit.b) Nonshielded cables. Nonshielded cables (i.e., those having no external metallic or sem

34、iconductingcoverings over the insulation) shall be tested with the active length (test sample length) in conduc-tive water that serves as the outer electrode. As an alternative, the cable may be tested in air after ithas been prepared with semiconducting tape or paint and metal braid or mesh as an o

35、uter electrode.4.3 Sample terminationsIf a cable or joint is being evaluated, end preparations may be test terminals, such as water terminals or resis-tive terminals. If a cable system is being evaluated, the active length shall include at least one of each type ofcommercial termination designated f

36、or use on the cable system.Preparation of test terminations should be conservative but adequate to ensure a test failure in the activelength of the cable or the cable accessory being tested.5. Test procedures5.1 Test temperatureThe temperature of the cable conductor shall be maintained at a constant

37、 value during the test. The tempera-ture of the cable conductor shall be set at the recommended maximum continuous operating temperature (+5C, 0 C) unless otherwise agreed upon. Other specifications may require individual cable system compo-nents to be tested at temperatures other than the maximum continuous operating temperature. Temperaturecontrol by conductor heating is preferred. External heating is allowed only by agreement between the par-ties. DC service application cable systems require conductor heating.Copyright 2003 IEEE. All rights reserved. 3
