Teacher: Prof. Arturo Losi
Credits: 6 ECTS (48 contact hours)
Suggested prerequisites: Basics of circuit theory (Ohm’s and Kirchhoff’s laws), basic theory of steady-state sinusoidal operation;
Aims: Students will gain the basic understanding of the operation and design of electric distribution systems and of electrical safety .
Contents: Structure of electric power systems: subsystems and functions, voltage levels. Distribution systems: components, topologies. Basic design of distribution systems for normal operating conditions: loading factors; voltage drop; line ampacity. Basic design of distribution systems for abnormal operating conditions: protection systems; overcurrent protection of lines. Electrical safety: effects of the current in the human body; current in the ground; touch and step voltages; protection against direct and indirect contacts.
