Abstract
A method and a device for detecting the degree of pollution in an operational converter are disclosed. An operating state of at least one of the converter components that is exposed to the ambient air is determined and a corresponding operating state of said component in an unpolluted state is determined. The two operating states are then compared and the calculated comparison value is used as a measurement for the degree of pollution of the converter. Detecting the degree of pollution of an operational converter permits a reduction in the number of breakdowns caused by unprotected operation of a converter, and associated disadvantages such as costs and damage to a company's image.
