What is creepage distance on High Voltage insulators?
Direct Answer
Option D: Shortest distance along outer surface of insulating material between two conductive parts
Creepage distance is the shortest path between two conductive parts measured along the surface of the insulation. Maintaining adequate creepage is vital to prevent tracking and flashover, especially in the humid, salt-laden marine environment, which can otherwise lead to insulation failure and dangerous electrical faults in HV switchgear.
