IEEE C37.63-1997

This standard applies to all overhead, pad-mounted, dry-vault, and submersible single-pole or multipole alternating current automatic line sectionalizers for rated maximum voltages above 1000 Vac. In order to simplify the vocabulary of this standard, the term sectionalizer has been substituted for automatic line sectionalizer wherever possible. Revision Standard - Superseded. Required definitions (for cutout type sectionalizers), ratings, procedures for performing design tests and production tests, constructional requirements, and application considerations for overhead and pad-mounted, dry-vault, and submersible automatic line sectionalizers for ac systems are specified. Keywords: sectionalizers, cutout type, dry-vault sectionalizers, pad-mounted, submersible
