Abstract
For the condition evaluation of an electrical insulation system diagnostic expert systems are
used. The positive aspects of these systems are the non-destructive and online operating
modus. In some cases the measuring results do not lead to an expressive decision, then
destructive tests enables a better estimation of the condition and residual life time. The life
time behaviour of an electric insulation system can be mathematically described by the so
called life characteristic curve. This model bases on the exponential characteristic of natural
processes for aging mechanism, which was already described by the law of Arrhenius. The
determination of this curve can be done with successive discharge tests and long-time
breakdown tests. To achieve a statistic correct result it is important to ensure that only wear-
out failures and no early and random failures are included to the examination. The reason for
the necessity of this differentiation finds its reason in the miscellaneous kinds of breakdown
respectively aging processes
