Dear anybody

turbine type: Siemens sgt8000 V94.2.

Recently we have been dealing with a strange fail trip in ASI robicon SFC (static frequency starter) during the startup of Siemens gas turbine type: V94.2, with this description: control fail I''dc<I'dc output current of converter is lower than input current of it. and it causes trip of the turbine at 160rpm (during the startup). I look froward to hear a guidance to solve this issue.

Alarm description: "SFC control fail trip"

thanks in advance.
