Please I need answers to this issue.
I operate an LM2500 stevenson & Stewartson GE GAS TURBINE in my firm and the issue here is our proximitors (Vibration sensors) is indicating an alarm that means when it gets to a reading of 4mils the Gas turbine will trip and that we are avoiding cos it's a huge loss
it has passed the alarm level of 3.0mils approaching 4mils.
we have 2 of these sensors the second ones reading is okay they are both located at the Drive End (DE) of the Generator section and it's reading 2.5- 2.9 mils which is okay for now,but the one in concern is reading above 3.6mils and 4mils the whole power trips.
please if you have any professional idea I'll really appreciate it, without shutting down the Gas Turbine to fix the fault.
thankyou
