The presence of normally distributed random fluctuations in power system signals can be used to extract valuable information about the condition of system equipment. One such component is the power cable, which is the primary focus of this work. This paper describes a unique methodology that allows online monitoring of a power cable. It uses frequency domain analysis techniques on the voltage signal...
Power system current and voltage signals contain valuable information about the system status within their small random fluctuations. Frequency domain analysis of these so-called noise signals enables us to monitor the power cable health. This paper proposes a new passive methodology for online power cable diagnosis by resonant frequency analysis. The feasibility of this methodology is proved by analytic...
