Course content
Properties of different insulation systems based on: gas, solids and liquid/paper. Mechanisms of electrical conduction, polarisation, dielectric loss and breakdown. Ageing mechanisms (partial discharges, thermal degradation,water treeing, etc.) and methods for condition assessment including environmental aspects.
Learning outcome
The course aims to give an introduction to properties of different insulating materials used for design of High Voltage apparatus.
Knowledge:
After completing this course the candidate shall:
- know the basic terms regarding determining dimensions of high voltage power apparatus.
- be able to give an account of the basic breakdown mechanisms of gasses, oils and solid insulating materials.
- be able to give an account of relevant factors determining permittivity and dielectric loss values.
- know the structure and characteristic properties of insulation systems based upon different polymers, glass, ceramics, oils and gasses.
- be able to give an account of the gradual degradation mechanisms caused by partial discharges, water trees and electrical trees.
Skills:
After completing this course the candidate shall be able to design insulation systems for simplified high voltage power apparatus.
The student will also have increased his/hers abilities to use instruments and equipment in the laboratory.
Learning methods and activities
Lectures, compulsory audithorium- and laboratory exercises. The laboratory exercises cover the topics: - Measurement of dielectric loss and detection of partial discharges in airgaps. Electric breakdown strength of airgaps exposed to AC, DC and impulse high voltage. The course is given in English.
Compulsory assignments
