Course Description

Overview of insulating materials in high voltage equipment. Electrical insulation systems and design concepts. Degradation mechanisms and defects. Basic methods for diagnostics and monitoring based on insulation resistance, loss tangent, and capacitance. Advanced methods based on dielectric spectroscopy, polarisation and depolarisation currents, recovery voltage. Partial discharge measurements based on oscilloscope techniques, phase resolved acquisition techniques, acoustical PD measurements, PD localisation. On-line techniques. Chemical and physical analyzing methods. High voltage test methods: AC, DC and impulse. Power equipment: generators, breakers, transformers, cables, capacitors, outdoor insulation, etc. Participants also learn how to choose the right solution for badly performing insulators in high voltage stations and lines. When the right actions and procedures are selected using a full understanding of the background data, and how targeted maintenance can improve the performance of insulators and bushings with pollution and wetting problems
