Fundamentals of 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 for determination of the of electric field intensity. Dielectric strength of the insulation. Discharge in homogeneous and non-homogeneous fields. Partial discharges, discharges occurring in nature, origin and types of lightning. Insulating materials, gaseous dielectrics and hard insulating materials. Distribution of potential along long structures, insulator chains and transformer coils.

The generation and measurement of high alternating voltages. Generation and measurement of high dc voltages. Generation and measurement of impulse voltages.

The sources 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.
