Aims and
Scope
The course aims to introduce the students in the technology of electrical
installations and the different aspects of the design and use of electrical
power equipment in energy applications. The scope is to familiarize students
with the necessary theoretical knowledge and the regulations applicable to low
voltage and medium voltage electrical installations, emphasizing in protection
and safety measures. The students should be able to study typical electrical
installations and perform all required
calculations according to regulations.
Course Description
Theoretical course
Regulations of low voltage
electrical installations. Security and protection measures according to
regulations. Earthing facilities in low and medium voltage. Earthing schemes
(TN, TT, IT TN-S, TN-C, etc.). Calculations of touch voltage and fault
currents. Insulated conductors and cables. Calculations (cross-section, voltage
drop, fault current carrying capacity). Elements of low and medium voltage
equipment (disconnectors, switches, circuit breakers, fuses, relays, etc.).
Calculations for the right choice of equipment. Domestic and commercial low
voltage installations. Design and calculations. Control and automation.
Lighting installations. Additional electrical equipment (communications,
electro, supervision and safety areas, fire - fire, etc.). Power factor
correction. Power supply schemes, uninterruptible power supplies. Medium
voltage consumers and substations. Calculations for the selection of equipment.
Laboratory course
The laboratory part of the
course will introduce students to standard low voltage installation tests that
will be carried out according to regulations in order to test reliability and
proper operation of equipment. Moreover, the students will be familiarized with
common automation circuits including programmable logic controllers.
Expected
Course Outcome
At the end of the course the
students will:
·
Be able to understand the basic theoretical principles and regulations
applied in typical low voltage and medium voltage electrical installations
·
Be able to apply this knowledge in practice to study and design typical
domestic, commercial or industrial electrical installations.
