Dry Arcing Length of Insulators
Dry Arcing Length of Insulators
(OP)
Dear friends,
Can any one tell me how to calculate minimum dry arcing length required to be sufficient to prevent flash over in EHV transmission towers insulator strings?(say 380kV), (for instance) creepage requirement is 40mm/kV.
