High Voltage Engineering

The main topic of the course is the analysis of the behaviour of insulators in high-voltage networks. 

The electric field in high voltage engineering, methods and procedures to determine the electric field. Dielectric strength and insulation withstand. Discharges in homogeneous and inhomogeneous field. Partial discharges, atmospheric discharges, origin and type of lighting strokes. 

 Insulating materials, gaseous dielectrics, solid and liquid insulating materials. Methods for isolation quality assessment. Distribution of potential along the long structures, ceramic type suspension insulators, transformer windings. 

Generation and measurement of high AC voltages. Generation and measurement of high DC voltages. Generation and measurement of high impulse voltages. The formation of overvoltage, lightning overvoltage, system overvoltage.  

Surge arresters and insulation coordination. 

Analysis of high voltage transients. High-voltage DC transmission. 

The student will learn the importance of high voltage in the design and operation of electricity networks and devices and will also acquire the basic knowledge of high voltage technology and methods for testing high voltage electric power equipment in the lab.

Lectures, tutorials and laboratory practice.
