Abstract
Partial discharges are symptomatic of many degradation
phenomena in power cables and can cause further deterioration of
the insulation in many cases. The partial discharges may be detected
by using online and offline techniques. However, offline techniques
have a significant disadvantage in that they require the cables to be
taken out of circuit. Hence, electricity supply companies prefer the
use of online techniques. The downside is that online techniques
have their own disadvantages e.g. interference, ambiguity of partial
discharge location, and sensor optimisation difficulties. The paper
provides an overview of the current state of the art in partial
discharge detection and location and also suggests how some of the
disadvantages of online detection and location might be overcome
