Presentation the electrical energy is produced, transported and distributed in the form of Ac. The electrical power at the plant is delivered to consumers through an extensive network of transport and distribution. Then.. What is an electric substation?
5 substation main tasks of substations the protection of the transmission system. Control of the energy exchange. analysis Voltage Fault reliable supply control

8. the bus bars an electrical conductor that establishes a common connection between several circuits. Plan single Bus Bar Simple transfer plan main Double main Busbar system
9. insulators Isolator is a mechanical switch that isolates a part of the circuit of the system in case of need. ((1) double break Isolator 2) Simple break Isolator 3) pantograph Isolator Type.
10. insulators it provide isolation between the conductors of line and supports and prevent thus any current leakage of the driver to the ground. PURPOSE SUPPORT BREAK TYPE CURRENT EQUIPMENT INSULATION 1. PIN Insulator 2. Suspension Insulator 3. Insulator
circuit breaker 11. Circuit the main function of the CIRCUIT BREAKER 1. it carries DC without heating 2.Opens or close the circuit in case of need. 3. it protects the circuit in the event of default.
