Abstract

The paper is focused on the short voltage dips and interruptions in the public supply networks and their influence on the connected computer power sources. There is performed a comparison of the immunity classification by standard EN 61000-4-11 against proposed immunity classification, which is based on the disturbing influences in real supply networks. There are mentioned specifications of the essential phenomena, which have influence on the final limiting curve of immunity. Limiting curves of some types of electric equipments are measured and pointed.
