Comparative Tracking Index
Creepage distance requirement depends on the CTI. Material which CTI is unknown are classified in IIIb group. In terms of clearance, a higher CTI value means a lower minimum creepage distance required, and the closer two conductive parts can be. wikipedia.org

Frictional contact mechanics
Johnson presented an approximate approach for the 3D frictional problem with Hertzian geometry, with either lateral or spin creepage. In case of a positive force (negative creepage ) it is: The size of the adhesion area depends on the creepage, the wheel radius and the friction coefficient wikipedia.org

Overhead power line
Longer insulators with longer creepage distance for leakage current, are required in these cases. Also, studies have shown that the specific creepage distance required in polymer insulators is much lower than that required in porcelain or glass. wikipedia.org
