High Voltage Equipment

MSc - NTNU

3–6 Months

Masters of Science Programes

Course Overview

The course gives a comprehensive introduction to the technologies that are employed in switching equipment, 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.

Main Goal

The course covers all important aspects of high voltage engineering in electric power system components.

Skills to be Gained

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, and perform dimensioning calculations for substations, transformer stations and cable installations.
