DESCRIPTION
Ensure that you are informed and a part of this leading edge technology by attending our two-day workshop presenting an objective, unbiased view of the latest and future developments in this area of electrical engineering. Distribution and Substation Automation offers you a multitude of benefits including: Increased function and reliability of electrical protection Advanced disturbance and event recording capabilities aiding in detailed electrical fault analyses Display of real-time substation information in a central control centre Remote switching and advanced supervisory control over the power network Increased integrity and safety of the electrical power network, including advanced interlocking functions Advanced automation functions e.g. intelligent load shedding This workshop is designed to familiarise you with all aspects of distribution and substation automation. The different levels of substation integration and automation are outlined and discussed. The components and architecture of the typical distribution and substation automation system are detailed. The different approaches promoted by the different substation automation vendors are identified and detailed and the advantages of each are outlined. The characteristics and operation of the Intelligent Electronic Devices (IEDs) are examined. A practical checklist is then provided of the optimum way to implement this technology to your next project.

Repeaters
• Connect two segments of the same LAN
• Simply amplify and retransmit the signal to the next segment.
• Repeaters connect different segments...but all segments form one LAN.

Bridges• Connect two networks.
• Bridge acts as a node as far as each network is concerned.
• More intelligent than repeaters and can reduce the traffic.

Routers
• Transfer data between different networks and route packets to the correct network to which they are attached.
• This is based on the Network layer (OSI Model).
Technology Training that WorksTechnology Training that Workswww.idc-online.com/slideshare
Gateway• Connect networks which are totally dissimilar.
• There may be a need to translate all 7 OSI layers.
• High overhead and to be avoided where possible.
• Expensive and low performance.
