Course content

The course gives a comprehensive introduction to the technologies that are employed in switching equipment, underground power cables and power transformers. The switching equipment sections cover switching over-voltages, the electric arc, arcing media (SF6, vacuum, air, oil), breaker designs, fuses, as well as gas insulated and air insulated substations. The cable part describes various designs and technologies used for underground and subsea cables, mechanical- and electrical stress, power rating evaluations and cable termination and splicing. The transformer section covers the electric insulation system, stresses during transient over-voltages, thermal aspects, protection, winding connections, and standards for transformer testing.

Learning outcome

Knowledge: After having completed the course the candidate should have advanced knowledge regarding: - design, working priciples and operation of switching equipment, power cables and power transformers - material usage in switching equipment, power cables and power transformers - the electrical, mechanical and thermal stresses that switching equipment, power cables and power transformers are exposed to. Skills: After having completed the course the candidate shall be able to: - participate in planning and specification of substations, transformer stations and cable installations in high voltage grids - perform dimensioning calculations for substations, transformer stations and cable installations - be able to use selected simulation tools for calculation of either thermal, mechanical or electric stress. - participate in design and development work on switchgear, cables and transformers - do marketing and sale of switching equipment, power cables and transformers. General competence: After completing the course, the candidate has increased: - ability to contribute to innovation and innovation processes

Learning methods and activities
