Abstract
A smart, self-feeding fuse with current detection and communication capabilities for use in overhead medium voltage electrical distribution networks (15 kV to 34 kV). The device is configured to detect transient or permanent electric faults (sensor), and/or to be used as a communication device (gateway) that preserves the main protection function of the fuse element. The device is assembled on a base fuse and is simply installed by using a maneuver pole, similarly to the installation of a conventional fuse tube. The invention is self-fed by a high output current transformer with the help of photovoltaic cells, using a supercapacitor bank as the only power storage element.
