This paper presents a review on condition assessment of
some of the most critical components in the power grid
today, such as transformers, rotating machines and
cables and their accessories. The main purpose is to
identify methods that can be applicable for high voltage
equipment for subsea use. The question addressed is
what diagnostic tools should be used to detect
apparatuses with a high probability of failure during
service.
It is shown that today, only distributed temperature
sensing systems are used for subsea applications. At the
same time, the majority of condition assessment
techniques used onshore can be adjusted for subsea use,
particularly methods applicable for on-line monitoring.
