Teacher: Prof. Arturo Losi

Type: Optional

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.
