Abstract
A node for detecting local anomalies in an overhead power grid having at least one power line. The node includes a processing unit and a memory, wherein the node further includes: an electric field sensor configured to measure a first parameter related to an electric field around the at least one power line, and a magnetic field sensor configured to measure at least second parameter related to a magnetic field around the at least one power line. The processing unit is configured to: compare the measured first parameter and at least second parameter with historic data stored in the memory to identify local anomalies, and forward data related to the identified local anomalies to a system controller via a communication interface.
