Hypothesis
The study investigates how pulsed electric fields affect bubble development and electrical treeing in silicone gels.
Conclusion
The research establishes that bubble discharge significantly influences the electrical treeing process in silicone gels under pulsed electric fields.
Supporting Evidence
- Bubbles in silicone gel can lead to electrical treeing, which degrades insulation properties.
- The study developed a two-dimensional model to simulate bubble discharge in silicone gels.
- Different pulse edge times significantly affect the initiation voltage for electrical treeing.
- Ozone generation during discharge is linked to the degradation of silicone gels.
- Shorter pulse edge times increase the breakdown voltage and discharge current.
Takeaway
When electric fields are applied to silicone gels, bubbles can form and grow, which can lead to electrical failures. This study helps us understand how to make better materials for electronics.
Methodology
The study used a testing platform to analyze bubble formation and electrical treeing in silicone gels under various pulsed electric field conditions.
