This Standard applies to all overhead, pad mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers and fault interrupters for rated maximum voltages above 1000 V and up to 38 kV. The following is also included in section 1: In order to simplify this standard where possible, the term recloser/FI (reclosers/FIs) has been substituted for automatic circuit recloser or fault interrupter or both. NOTE–When reclosers are applied in substation, special considerations may apply.
The purpose of this project is to revise existing standard including, but not limited to: a) general update to bring the standard in line with current technology; b) update information on BIL, altitude correction, temperature rise; c) add information on other interrupting/insulating media (e.g. SF6); d) add transient recovery voltage requirements; e) add voltage ratings common to systems outside of North America
Revision Standard – Superseded. This Standard applies to all overhead, pad mounted, dry vault and submersible single or multi-pole alternating current automatic circuit reclosers and fault interrupters for rated maximum voltages above 1000 V and up to 38 kV.
