Substation

アプリケーションの概要

Power utilities commonly utilize Gigabit-speed Ethernet systems in substations for automatic control, protection, remote maintenance and disturbance analysis. These systems are mission critical requiring ruggedized, redundant networks to ensure maximum system reliability.

考慮事項

  • Industrial grade switches for protection against ESD and certified with EMI/EMC protection with overvoltage and overcurrent protection.
  • Low maintenance costs (OPEX) with remote management functions.
  • Auto-provisioning to update the firmware for the entire network, rather than only a single switch.
  • Precise synchronization as per IEEE 1588v2 to simplify integration of all functions.
  • Extensive management and filter functions with a variety of redundancy protocols and port security.
