This Network Standard provides guidelines for design of optical cabling infrastructure within the boundaries of Ausgrid substations and depots. The equipment specified in this Network Standard is supplied under present procurement arrangements by Australian Fibreoptic. . remote management of Arctic gateways, controllers and the remote I/O unit RIO600. Arctic Patrol allows simultaneous updating of both the configuration and the firmware of up to 1,000 dication, power quality analysis in medium-voltage secondary distribution systems. It applies to greenfield sites and major augmentations. . A secure, reliable, and economical power supply is closely linked to a fast, efficient, and dependable communications infrastructure. The planning and implementation of communications networks require the same attention as the installation of the power supply systems themselves. New challenges for. . For issue to all Ausgrid and Accredited Service Providers' staff involved with the design of Ausgrid's major substations, and is for reference by field, technical and engineering staff. A substation automation system also automates some repetitive, tedious and error-prone activities to increase the overall. . To enable reliable and secure power supply, modern substation communication networks follow the IEC 61850 Standard to provide interoperability between various equipment, and enables advanced functionalities such as wide-area protection and control, fault location, and disturbance recording.
