Abstract
A device and method for fuse protection of a line includes at least two sensors for sensing a corresponding electric variable in a first location and a second location along a conductor line, and for outputting a corresponding first value and second value of the electric variable at the first and second locations, respectively. An evaluation unit evaluates the generated first and second values in order to generate an evaluation result. The evaluation unit controls, based on the evaluation result, an isolating element to cause the isolating element to interrupt a current flow in the conductor line.
Claims15
A device for fuse protection of an electrical conductor line, comprising:
- at least two sensors for sensing a corresponding electric variable in a first location and a second location along the conductor line and for outputting a corresponding first value and second value of the electric variable at the first and second locations, respectively;
- and
- an evaluation unit that compares a difference between the generated first and second values to generate a first comparison result, and compares the first comparison result with a predefined threshold value to generate an evaluation result, wherein the evaluation unit controls, based on the evaluation result, an isolating element to cause the isolating element to interrupt a current flow in the conductor line.
