This specification describes the features and ratings of the NOVA recloser. The NOVA recloser shall be a three-phase electronically controlled recloser suitable for pole or substation mounting. It shall utilize shatter-resistant outdoor cycloaliphatic epoxy encapsulated axial-field vacuum interrupters. Current sensing shall be provided by three internally encapsulated current transformers. The NOVA recloser shall be available with optional Internal Voltage Sensing. The Form 6 or Form 4D electronic control, coupled with the NOVA recloser, constitutes the NOVA recloser system.
The NOVA Recloser shall be designed and tested in accordance with the following standards as applicable:
IEEE Std C37.60™-2003 standard – IEEE Standard Requirements for Overhead, Pad-Mounted, Dry Vault and Submersible Automatic Circuit Reclosers and Fault Interrupters for Alternating Current Systems
ANSI C37.61-1973/IEEE Std 321™-1973 standard – IEEE Standard Guide for the Application, Operation, and Maintenance of Automatic Circuit Reclosers.
ANSI C37.85-2002 – American National Standard Safety Requirements for X-Radiation Limits for AC High-Voltage Power Switchgear.
