Course description

The course aims to provide the basic concepts related to metrology and power quality problems as well as tools needed to analyze the problems of electrical safety.


1. Knowledge and understanding
The student must know:
- the general criteria of measurement and evaluation of power quality disturbances
- the laws on the electrical safety.
- the general criteria for designing the protections against overcurrent and against direct and indirect contacts.

2. Applying knowledge and understanding
The student must demonstrate to be able
- to integrate knowledge in the field of power quality disturbances and electrical power systems.
- to apply the criteria for the selection and use of protective installation against electrical risk.

3. Making judgments
The student must demonstrate that he has the basic knowledge for dealing and deepening in an autonomous way the issues related to the power quality and electrical safety problems.

4. Communication skills
The student must demonstrate the ability to easily explain to people
- the methodologies for the evaluation and reduction of the power quality disturbances
- the solutions adopted in the electrical distribution systems for the achievement of prefixed safety levels.

5. Learning skills
The student must be able to update information about power quality and electrical safety problems through texts, standards and publications in order to acquire the ability to undertake further courses, specialized seminars and master


The student must have acquired the following knowledge provided by the courses of "Electrical circuits and Network Analysis" and "Electrical power systems":
The circuit model: ideal circuit elements, voltage and current. Kirchhoff’s laws. Linear resistive circuits: series and parallel equivalence, superposition principle, Thevénin-Norton’s theorem. Linear circuits in DC and AC steady state. Complex power, active power, reactive power, and conservation properties. Dynamical circuits, general methods of solution. Symmetric three-phase circuits: balanced, unbalanced.
Normal and abnormal operating conditions of an electrical power system; overcurrent and over voltage protection systems
