• What is Electric Network


� Substation is a node in the grid electric network

� Substation is linked to one voltage level

1. Dispatch power flow on

branch/lines

2. Allow maintenance

(line/device)

3. Select/eliminate fault in only one section

4. Mesh network (stability)

• Primary Device: Bus Bar� Feeder => interface to Voltage level (line branch, transformer)

� Bus Bar => Backbone to dispatch power between feeders


• Primary Device: Circuit Breaker� Make / Break Current then Power flow

� Operate under Nominal or Faulty condition - exploitation- shortcut current


• Primary Device: Bar / Line Isolator� Bar Isolator : Isolate CB / Bar (maintenance/exploitation)

� Line Isolator : Isolate CB / Line (line maintenance)

� Control => dispatch energy

=> keep service (continuity, quality)

=> maintenance operation

� Protection => Fault (Shortcut)

• Short circuit implies unbalancing, voltage drop…

• Isolate Faulty section

• Save device from destruction

• Secure installation fire / explosion (arc)people security (insulation)

� Protection => Exploitation (Overload)

• Unbalanced exploitation

• Damaging isolation

• Degrading devices

• Why protecting
