Cable termination faults are problematic in electrical networks almost always.
Technology has solved problems somewhat, but there are many annual reports about
damaged cable terminations. For analyzing the problems, faults in two regional electricity
companies are studied. At first step, damaged cable terminations are analyzed statistically
and grouped according to their problems. Then, some of the damaged cable terminations
are checked to classify vulnerable areas. The investigation is completed by simulation,
analysis and study of equivalent circuit. Conclusions underline important points which can
be helpful for reducing the damages.
