The idea behind this series of lectures is to reveal the importance of each design phase and interlinks between them in the transformer life expectation of 30 years and more. This course provides the overview of the main design aspects.
Attend the session to learn about the following:
- Voltage shapes
- Volt time factors
- Weidmann curves
- Insulation outside the windings
- Insulation inside the windings
