Answer. IEC has established four degrees of pollution severity: Pollution Degree 1: No pollution or only dry, nonconductive pollution occurs. The pollution . “Insulation coordination for electrical equipment in low-voltage systems”.

Pollution degree 3 is a harsher environment typical in many industrial manufacturing areas. Pollution degree 3 is a harsher environment typical in many industrial manufacturing areas. Examples of pollution degree environments. Pollution degree is a classification according to the amount of dry pollution and condensation present in the environment.

Any equipment designed for, or placed in a test station environment should have a pollution degree 2 rating in order to 64-1 recognized safety standards. This site uses cookies to offer you a better browsing experience.

Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation occurs. Examples of pollution degree environments.

See table 1 for examples of each of these environments [2,3]. The pollution has no effect. The pollution generates persistent conductivity caused by conductive dust, rain, or snow. Examples of pollution degree environments Clearly, ATE environments i. Affect of Pollution degree on safety distances.
