As the official sponsor of this lesson, SGB SMIT GmbH will give their presentation during the live session. The content will also be visible once when the session is available on demand.
Here is what you can expect to learn this time:
Electrical insulation materials:
− Definition and types
− Properties
• Electric field and voltage distribution
• Methods to calculate electric field and voltage distribution
• Breakdown and partial discharges
• Dielectric tests and their purpose
• Highest voltage for equipment and rated insulation level
