Abstract

Cables are one of the main assets in the power grid
particularly for distribution network where the loads are widely
spaced, this is a vital issue in oil and gas power grid. Monitoring
cables on-line is an impossible task due to the cost and the
excessive number of distributed cables. In most of oil and gas
production countries the ambient temperature hits 56 degree
Celsius that adds to the failures of power cables and shorten the
cables lifecycle and the hour to hour capacity.
This paper presents the results of estimating the maximum
operating temperature of the cable during different operating load
and under different ambient temperature, it is anticipating its
impacts on the cables lifecycle. This is compared to the cable
manufacturer design specification associated with the normal
operating temperature. The results identify the factors contribute
significantly to the degradation of the physical insulation property
of the cables. In this paper the response time in the thermal
transient model is used to identify the remaining useful life (RUL)
of the cable. The model is used as a diagnostic procedure to detect
the degree of aging, the results show that RUL of underground
cables is 7.5 years and for overhead cables is 13.3 years under
ambient temperature of 47° C and maximum load current.
