ABSTRACT:
A current limiting protector for use in electric power transmission lines includes a conductive strip of material and a chemical charge for physically interrupting the conductive strip in response to a fault current. A current sensor triggers the chemical charge when the line current is symmetrical and the RMS value of the line current exceeds a first value, and the current sensor triggers the chemical charge when the line current is asymmetrical and the RMS value of line current exceeds a second value.
