The course provide the basic knowledge required for the usage of the most common electrical power systems

Fundamental of power systems: trend toward growing power output of new thermal, nuclear, alternative and water generating station, electrical distribution systems of great and low magnitude, single phase transmission and 3-phase transmission.
Engineering of electrical transmission lines: resistance, inductance, inductive reactance, capacitance, capacitive reactance. Transmission linear models: the short transmission line, the medium lenght line, the long transmission line. Power cables (low, medium, high and extremely high voltage). Low voltage cables ( good polymers and compoud workability, cost and competivity).
Fundamental of power flow solution: scope of power systems analysis, faults, protection and stability,
2)Engineering of industrial and civil ambient.
2A) Plans and sitework: Electrical project of civil and industrial ambient, construction plans, explanations of plan symbols and sitework.
2 B ) the unit substation: high voltage section, the transformation section, the low voltage section, high voltage meetering equipment.
2 C) feeder bus systems: feeder ducts, the circuit breaker cubicles, plug-in bus way, bus plugs, branch circuit.
