Summary

The Technical brochure shows that it is most important to control the electrical field near the HV and ground ends of Hv overhead line composite insulators. This can be achieved by fitting the insulator with corona rings. Their size and position are critical to correctly control the electrical field. The insulator manufacturer is best equipped to correctly define the dimensioning and location of these rings.
