4 Frequently Asked Questions about "Creepage distance of double glass modules"

Is there a physical relationship between creepage and clearance?

There is no physical relationship between the two, but the creepage distance cannot be less than the clearance distance. It is important to maximize both creepage and clearance whenever possible while considering the trade-offs of size and cost.

What is a minimum creepage?

The minimum creepage is at least the clearance. This is why the creepage length must be at least as large as the clearance in air. For inorganic insulating materials like glass or ceramic, which do not track, the creepage distance may equal the associated clearance. Solid insulation is insulation not created solely by air or gas.

What is the difference between creepage distance and clearance distance?

Creepage distance is measured along the surface of an insulating material in SPDs and MCBs, while clearance distance is measured through the air. This means that creepage distance is more affected by environmental factors such as surface contamination and humidity, whereas clearance distance is influenced mainly by air quality and pressure.

How do you choose a creepage distance?

The creepage distance should be selected based on the reference voltage, pollution level, and insulation material category. The reference voltage value is derived from the rated voltage of the power supply grid. What is the clearance distance?
