Grading devices for a high voltage apparatus |
摘要 |
An electrical assembly having an elongated electrical component, such as a surge arrester, coupled to a grading device for distributing an electric field along the electrical component as a continuous operating voltage is applied to the electrical component. The grading device includes a grading body that is coupled to the electrical component. The grading body includes semi-conductive materials. The semi-conductive materials can be nonmetallic. The grading device has improved flashover resistance over conventional metal grading devices. |
