| Summary: | The studies of the service life and residual life of various
insulating materials are described. The known mathematical
models of insulation aging applicable to AC power cable
lines are considered. Based on the models and the previously
proposed approach, the service life and residual life of cables
with XLPE, EPR and PVC insulation are estimated. The
assessment is carried out using the data from monitoring the
voltage and current of a 6 kV cable transmission line laid at
one of the electric power enterprises. Air temperature obtained
from open sources. The results showed the applicability of
all models for estimating the residual life due to the small
difference in the predicted life. In real conditions, the service
life of the listed types of insulation can be different due to
their dielectric and design features. |
