This comprehensive presentation, led by Antwi and Markus, delves into the critical aspects of transformer safety and the methods by which a high level of safety can be achieved in transformer design and application. Understanding and adhering to international safety standards is paramount, especially in power supply units (SMPS) where transformers play a crucial role. The presentation will particularly focus on the IEC 61558 safety standard and its implications.
The session will discuss:
- The safety standard IEC 61558 in direct relation to both transformer design principles and their application in Switch-Mode Power Supply (SMPS) units.
- The new aspects of the 2021 version of IEC 61558, which is yet to be fully released globally, providing an early insight into future requirements.
- A detailed presentation of the various IEC 61558 safety levels relevant to transformer design, specifically addressing:
- Overvoltage categories and their impact on insulation requirements.
- Precise requirements for creepage and clearance distances to prevent electrical breakdown.
- The importance and methodology of the partial discharge test for assessing insulation quality.
- The acceptance and harmonization of IEC 61558 with other relevant safety standards, such as IEC 62368.
