Abstract
The invention relates to a system for the data transmission of digital transmission data () between a first digital protective device () and a second digital protective device () on a section (A) of an energy supply line () in a transmission direction () and in a reception direction (). The first digital protective device () is connected to an end () of an electrical data transmission line () via a first coupling device (). The second digital protective device () is connected to the other end () of the electrical data transmission line () via a second coupling device (). In order to establish data transmission with little complication, the data transmission line () is one-paired, and both coupling devices () are adapted to enable transmission of digital transmission data in the transmission and reception direction (or) on the one-paired data transmission line () in the manner of a digital telecommunication transmission. The invention further relates to a method for transmitting data.
