  • Switchyards and Substations
    center where: electrical power is supplied to the plant from the outside, and. electrical power is sent from the plant. Often there are at least 2 main Buses. Very high voltages (typically 220,000 or 345,000 volts) are present. Gas and oil circuit breakers are used. The gas (e.g. sulfur hexaflouride
  • The Ethernet Checklist for Power Substations
    disruption to critical substation operations. A basic ring can be established for intelligent electronic devices (IEDs) that control electrical equipment such as protection relays, meters, and circuit breakers. For this architecture, each Ethernet switch would be connected in a ring topology and would run

  • Smart and Synchronized Substation Automation with IEEE 1588v2 Embedded Computers
    " is for the electrical infrastructure to be, well, smarter. For power substations, this means that computers will need to be at the front-end, connected to remote devices such as switch gears, sensors, power generators, and circuit breakers through intelligent electronic devices (IEDs). Other priority
