Abstract
A monitoring system for an electrical transmission and/or distribution network is disclosed. The system comprises a short-range wireless transceiver arranged at a predetermined position relative to an equipment device and configured to receive a signal from a portable device, and a controller configured to determine a location of the portable device based at least partially on the received signal. The controller is further configured to verify if the determined location is within a predetermined alert zone at least partly surrounding the equipment device, and to generate an alert signal in case the determined location is verified to be within the alert zone.
