The distance measure of along the surface of the solid insulating material is called creepage distance. The creepage distance is depending upon the weather condition. Minimum creepage distance are 16-25 mm/kV.
For the most part creepage is the primary concern when it comes to "high voltage" and PCB design. It pertains to the safe distance between two conductor of differing electrical potential & the dielectric strength of the medium separating them. For a given voltage, the distance that can safely & reliably support such a voltage is governed by ...
