Abstract
A circuit arrangement for identifying network zero crossings of a network voltage of an alternating current network is provided. A measurement current generated by the network voltage is supplied to a zero crossing detector in order to produce a network zero crossing signal. A current sink is arranged between a live conductor and a neutral conductor of the alternating current network, the current sink allowing the path of a current value of the measurement current generated by the network voltage to be defined.
