The Creepage Clearance Calculator helps in determining the required creepage distance between conductive parts based on different factors such as voltage, environment, and insulation class. Creepage distance is crucial for electrical safety and preventing electrical discharge or breakdowns.

Creepage Clearance Calculation Formula

The following formula is used to determine the creepage clearance:

Creepage Clearance = Voltage * Adjustment Factor

Variables:

  • Voltage: The operational voltage in volts (V)
  • Adjustment Factor: This factor varies based on the environment and other conditions

For advanced calculations, additional factors such as insulation class, pollution degree, and altitude are considered to adjust the base creepage distance.

What is Creepage Clearance?

Creepage clearance refers to the shortest path between two conductive parts along the surface of an insulating material. It is crucial for preventing electrical discharges and ensuring the safety and reliability of electrical systems.
