Abstract
The method for mains-synchronous switching of circuit breakers comprises the following method steps: measurement of the current flowing through a circuit breaker () and measurement of a mains voltage on a first side of the circuit breaker (), additional voltage measurement on a second side of the circuit breaker (), feeding of all the measurement signals to a control device (), deciding in the control device (), on the basis of the characteristic data stored there, which measurement signal will be used as the reference value for the mains-synchronous tripping of the circuit breaker (), generating a switching command, which initiates the mains-synchronous switching of the circuit breaker () on the basis of this decision, and carrying out the switching command by the circuit breaker ().
