Analytical Approach to Implementing Insulation Coordination
Abstract
In order to produce reliable power electronics in the range of 400 V - 500 V or in the future from 800 V - 1200 V, it is no longer enough just to follow the tables of standards that exist up to a maximum voltage of 60 V extrapolate.
In order to be able to determine the degree of contamination and thus indirectly the size and weight of the system, the actual risks for the respective assembly must be determined. For this purpose, the contamination on the surface and the insulation material must be assessed in terms of their respective manufacturing quality.
Discover the three key factors that form the foundation of the analytical risk assessment outlined in this white paper.
