OverviewInsulated conductors in service are subjected to voltage surges from lightning, switching, and other

32、 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 possible tocompare the impulse strength of different insulations measured by different labor

33、atories, at different times.2. ScopeThis test procedure applies to both switching impulse and lightning impulse tests on cables or cable systemsincorporating laminated or extruded insulations. The term laminated cable, as used in this procedure,includes: high-pressure pipe cable, low-pressure gas-fi

34、lled 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 any existing or future standards covering cable or cable acces-sories, impulse generators,

35、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 apply to cables or cable systems that utilize gas or gas spacers as the soleinsulating m

36、edium. This test procedure applies to individual cable accessories only when referenced by thespecific accessory standard.3. PurposeThis test procedure is intended as a guide for impulse testing of insulated conductors (cables) and cableswith accessories installed (cable systems). It can be used as

37、a design or qualification test for cables or cablesystems.14.
