Full Description
Scope
This test procedure applies to both switching impulse and lightning impulse tests on cables or cable systems incorporating laminated or extruded insulations. The term laminated 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 any existing or future standards covering cable or cable accessories, impulse generators, impulse testing, or voltage measurements. It is intended to supplement such standards 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 sole insulating medium. This test procedure applies to individual cable accessories only when referenced by the specific accessory standard.
Purpose
This test procedure is intended as a guide for impulse testing of insulated conductors (cables) and cables with accessories installed (cable systems). It can be used as a design or qualification test for cables or cable systems. The purpose of this revision is to change to metric measurements. We will also clarify and update the test and reporting procedures based on lab research and user experience since the previous publication.
Abstract
Revision Standard - Active.A test procedure for impulse testing of insulated conductors (cables) and cables with accessories installed (cable systems) is provided in this standard. This procedure can be used as a design or qualification test for cables or for cable systems. This test procedure is not intended to replace any existing or future standards covering cable or cable accessories, impulse generators, impulse testing, or voltage measurements. It is intended to supplement such standards by providing specific procedures for impulse testing on specific type of cables, accessories, or cable systems.
