Abstract:
An accessory device for an electronic protection relay comprising: a first communication port for communication with one or more electronic devices of the electronic protection relay or operatively connected with the electronic protection relay; a second communication port for communication with one or more computerized units through the Internet; a first processing means to manage the operation of the accessory device, the first processing means being operatively coupled with the first and second communication ports. The accessory device is configured to execute a data-gathering procedure (DGP), in which the accessory device polls one or more electronic devices, which are in communication with the accessory device through the first communication port, and receives grid data (D), which are related to the operation of an electric power distribution grid including the electronic protection relay, from the electronic devices in response to the polling. The accessory device is configured to execute a data-publishing procedure (DPP), in which the accessory device transmits the grid data (D) to a publishing computerized unit, which is in communication with the accessory device through the second communication port.
