Learning Outcomes:

This course provides the basic knowledge and techniques for the
preparation of design and
construction of internal electrical installations of buildings in
accordance with applicable
standards and national regulations, with the development of the
following topics:
• Basic concepts in electricity distribution systems. Electrification
process of low voltage
internal electrical installations, ways of connection to the PPC
network. Low voltage
overhead power line.
• Classification of indoor electrical installations. Calculation of
installed power. Categories of
pipes for indoor electrical installations, materials, components and
means of protection of
indoor electrical installations. Grounding systems and protection
against electric shock.
• Typical connections of luminaires, sockets and household
appliances. Complete calculation
of household electrical installation. Calculation of voltage drop
across conductors. Panels of
indoor household electrical installations.
• Low current installations.
• Outdoor installations. Installations of special buildings.
• Standards and Regulations of electrical installations. (HD384).
Control of an internal
electrical installations.
• Modern household electrical installations (EIB / KNX).
Study and design of electrical installations with a computer. The
student is required to
complete a series of selected laboratory exercises in the above
material. In addition, the
student is required to prepare and submit at the end of the
semester a written assignment
on the subject of electrical design of a building.
Upon successful completion of the course the student will be able
