SYN-7 Synchroniser Relay
The synchroniser relay SYN-7 adjusts voltage and frequency of a generator to the mains, in order to connect it at a minimum difference of frequency and voltage, and at the same phase position. Depending on its configuration, the SYN-7 is monitoring sense of rotation, voltage difference and asymmetry. Voltage measurement is done as 2-, 3- or 4- wire measurement, according to the preset parameterisation. The frequency measurement generally is on L1 and L2. In island mode, the desired frequency and voltage are internally set by the device. A separate variant of the SYN-7 is available for measuring voltages <= 100 V.
