Abstract
A method for operating a circuit breaker which protects an electric circuit is provided. The circuit breaker has a mechanical switch element and an electronic switch element connected in series thereto. In one step, the circuit is reactivated by the electronic switch element after being deactivated by the electronic switch element due to a short-circuit in the protected circuit, the short-circuit being detected by the circuit breaker. At least two current measurement values separated by a time interval are ascertained for the current flowing through the circuit breaker, and two voltage values separated by a time interval are ascertained for load-side terminals of the electronic circuit breaker. The circuit is deactivated again by the electronic switch element when criteria. Finally, the impedance of the line between the circuit breaker and the short-circuit location is calculated from the voltage values and the current measurement values and the time interval thereof.
