Subject description


  • The prerequisite for the course is the enrolment in the second year. The prerequisite for the oral exam is a positive assessment of tutorials report.

Content (Syllabus outline):

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 field. Partial discharges, discharges occurring in nature, origin and types of lightning. Insulating materials, gaseous dielectrics, and hard insulating materials. Methods for determination of insulation condition. 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 voltage. Generation and measurement of power surge. The formation of overvoltage, lightning overvoltage, system overvoltage. Surge arresters and insulation coordination. Modeling of high-voltage devices and networks and analysis of high-voltage transients.

Objectives and competences:

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-technology and methods for testing high-voltage electric power equipment in the lab.

Intended learning outcomes:

  • Knowledge and understanding: The student will understand the importance of high voltage for planning and operation of the power network. The student will also learn about testing methods for electricity equipment testing in a high voltage laboratory.
  • Application: Prerequisites for further study and practical application at high voltage equipment testing.
  • Reflection: Understanding the connection between high voltage, equipment design and structure of the power network.
  • Transferable skills: Knowledge of measurements procedure and report generation is useful in the frame of various measurements.

Learning and teaching methods:

  • Lectures,
  • tutorials (laboratory work).
