Abstract
Abstract-This paper presents the remaining lifetime calculation
of power transformers paper insulation and consequently of
power transformers. The calculations are performed based on
two models, which are related to the thermal degradation of the
cellulose winding paper insulation: the common IEC loading
guide and a paper degradation model. The paper insulation
model’s prediction can be improved by involving data from
furfural analysis.
The remaining lifetime is extracted from the fault probability
(reliability) of the paper insulation. The two models are brought
together, to aid the asset manager in the decision making
process. A probabilistic approach is used, which can be coupled
to analysis in terms of risks, benefits, costs, and availability by
the asset manager.
