This guide covers devices that are being used in secondary network systems protection schemes. These devices act to sense the fault and initiate fault interruption locally or remotely, thereby reducing damage and restoration time. This guide is intended to aid engineers who design protection of secondary network systems. Revision Standard - Active. Current available devices that are being used in secondary network systems protections schemes are covered in this guide. These devices act to sense the fault and initiate fault interruption locally or remotely, thereby minimizing damage and restoration time.
