If plant conditions of the voltage transformers connected in open delta connection (V-connection) are avail-
able, it is recommended the following connection. In terms of electricity, there is no difference for the
synchronization function to be connected to a three-phase voltage transformer. Essentially, it is also possible a
mixed connection. On the one side three-phase isolated voltage transformer and on the other side V-connec-
tion. If synchroscope is additionally connected, it is necessary a galvanically isolation via an interposing trans-
former.
