Figure. 5.2.1 - 45. Setting group control – two-wire connection from Petersen coil status with additional logic.
The images above depict a two-wire connection from the Petersen coil: the two images at the top
show a direct connection, while the two images on the bottom include additional logic. With a two-wire
connection the state of the Petersen coil can be monitored more securely. The additional logic ensures
that a single wire loss will not affect the correct setting group selection.
The application-controlled setting group change can also be applied entirely from the relay's internal
logics. For example, the setting group change can be based on the cold load pick-up function (see the
image below).
