Summary
DescriptionCorona rings on insulators.png
English: Insulator strings supporting a 225 kV power transmission line near Fessenheim nuclear power station, France. The metal rings around the top and bottom of the insulators are called corona rings. They serve to reduce the potential gradient at sharp points to prevent corona discharge, a leakage of current into the air.
Español: Aisladores de disco en una línea de 225.000 voltios.
