Abstract
A line protection device includes terminals to connect the line protection device in series with an electric line. A current sensor of the line protection device senses a value of electric current through the electric line. A digital filter circuit of the line protection device performs digital filtering of the value of electric current. Depending on the digitally filtered value of the electric current, a switch control circuit of the line protection device controls a switch to interrupt flow of the electric current through the line.
