    7. Objectives, learning outcomes and obtained knowledge

    The course presents the state-of-the-art insulating materials and their applications. Requirements to insulating materials applied in different industries, especially the electrostatic hazards and the prerequisites of the application in electric power generation, distribution and consumption. Inspection of insulating materials and insulations.

    8. Synopsis

    Week 1: Introduction. Condition of apparatus and equipment and the effect of insulation ageing.

    Week 2: Conducting, insulating and dissipative materials; electrical and non-electrical properties of insulating materials.

    Week 3: Organic and inorganic insulating materials, their conducting and polarization properties.

    Week 4: Measurement techniques of electrical material properties.

    Week 5: Electrostatic charging. The development and types of electrostatic discharges.

    Week 6: Dangers posed by ESD in different industries. Protection against the hazards of ESD. Electrostatic measurements.

    Week 7: Ageing of insulations, changing of their properties due to stresses. Basics of processes leading to insulation failure.

    Week 8: Basic models of thermal and electrical ageing. Effect of moistening.

    Week 9: Insulation diagnostics, measurement of dielectric properties. DC measurements: methods based on current and voltage measurement. AC testing: capacity, loss factor an complex permittivity measurements.

    Week 10: Types of partial discharges and their relation to the condition of the apparatus. Measurement methods: electrical and non-electrical. Insulation testing with reflectometry.

    Week 11: Diagnostic measurements and their evaluation in case of different apparatus.

    Week 12: Diagnostic measurements of switchgears: arc quenching and insulating medium, conductivity (condition of contacts), insulating ability, condition of the drive (static and dynamic properties), tests of secondary equipment.

    Week 13: Asset management techniques of transmission and distribution equipment.

    Week 14: De-energized and live maintenance at different voltage levels. Inspection of live work tools.
