We have frame 6 GE Gas Turbine, suddenly while we are in normal opeation it was tripped on exhaust temp. high alarm although the exhaust temp is showing normal reading during this time. We replaced one thermocouple that gives the alarm to kill the doubt even we know that one thermocouple will not make trip. After that we started the turbine and everything is normal.
Can anyone give advice about what we can do and what the cause of this trip as there is no indication. Could the scantime of the I station cause it not to detect a fast trip and the exhuast temp. really increased?
Thanks for all. My mail: hanywepco @ yahoo. com
