Tan-Delta also called loss angle OR Dissipation factor
testing is a diagnositic method of testing cables to
determine the quality of the cable insulation.This is done
to try to predict the remaining life expectancy and in
order to prioritize cable replacement and/or injection.It
is also useful for determining what other tests may be
worthwhile.
