The high voltage (HV) bushings are sensitive components of power transformers because they provide electrical insulation between the HV line and grounded tank and offer necessary mechanical support. Most of transformer breakdowns are attributed to the HV bushings failures which are graded with conductive layers to improve their dielectric strength. The design of bushings is quite challenging with trade-off between several factors like the axial and radial electric stresses, used materials for insulation, transformer tank configuration to meet internal and external flashover clearances and creepage requirements.

In this webinar, we will show you how our electromagnetic simulation package can help engineers to design and study their high voltage bushing and insulator systems.
