Short-circuit sensor

Abstract

The present disclosure relates to a short-circuit sensor for detecting a short-circuit current in an electrical line. The short-circuit sensor includes an integrator, a coupling device, and a detection device. The coupling device is configured to inductively couple the integrator to the electrical line and to supply an induced signal to the integrator. The integrator is configured to integrate the induced signal to obtain an integrated signal. The detection device is configured to compare an amplitude value of the integrated signal with a prescribed threshold value and to detect the short-circuit current if the amplitude value of the integrated signal exceeds the prescribed threshold value.
