No or only dry, non-conductive pollution. Pollution has no effect
Usually only non-conductive contamination occurs. The occasional occurrence of temporary conductivity
caused by condensation must also be taken into account
There is the occurrence of conductive pollution or dry non-conductive pollution that turns conductive due
