What is clearance and creepage distance ?

Clearance is shortest distance in air and Creepage is shortest distance along the surface of a solid insulating material, between two conductive parts.

Clearance is the shortest distance in air between two conductive parts.

Factors affecting Clerance :

  • Overvoltage Category
  • Altitude
  • Temperature
  • Operating Voltage
  • Fields of Operation
  • Overvoltage

Creepage is the shortest distance along the surface of a solid insulating material between two conductive parts.

Factors affecting Crepage :

  • Pollution Degree – Humidity & Dust
  • Comparative Tracking Index (CTI)
