    摘要: A method for controlling the parallel running of a plurality of transformers T1, T2,…, TN) in a parallel circuit (10) is disclosed, wherein each of the transformers (T1, T2,…, TN) is assigned a measuring/control device (12) and all the measuring/control devices (12) are connected to one another via a communication connection (16). In the absence of a standby signal of at least one measuring/control device (12), interruption (16) of the communication (14) is displayed. The measured values determined at the time (t) of the interruption remain constant for the duration of the interruption (16) and are also included in the calculation of the control errors during the interruption (16), in order to minimise a circuit reactive current of the transformers (T1, T2,…, TN).
