The relay's protection function parameters can be set and the active setting groups can be changed by an IEC 61850 client using the standard IEC 61850 services. The disturbance recorder and load profile files in COMTRADE format are retrieved from the \COMTRADE\ and directories by using PCM600 or any other client supporting IEC 61850 file transfer service or FTP.
When setting the parameter to “Primary”, the values sent over IEC 61850 are scaled according to the CT and VT settings.
Note: Restart the protection relay after changing the parameter. This feature is needed if the SCADA system or substation gateway does not handle scaling from nominal values.
