    ArcNET Jumper Configuration

    Greetings to all, We have GE Frame V Mark V Turbines. We need to make a spare unit of <I> PC. We did take a copy of the hard drive to another one running in Pentium CPU. The OS is IDOS. The problem is when we try the PC on the turbine, it stops when it calls the ArcNet definition file. We...

    Turbine Air Inlet Filter Pulse Cleaning

    Dear CSA, We have GE Frame 5 Gas Turbines. The pulse air cleaning system is similar to what you described above. We have 3 pressure switches 63TF-1 (Set. 11.3mbar) & 63TF-2A/2B (Set. 30 and 32 mbar). The first one initiates an alarm, while the turbine trips on 2 out of 3. We are located in...

    Combined SRV/GCV

    Hello, Is it the assembly used by Frame 5 and manufactured by Young and Franklin? We recently contacted them to provide any information, but they replied that valve overhaul is 'risky' to be performed on-site and they can share any information regarding the process (clearances, tools, ...)...

    Anti-static Device in Ball Valve

    Greetings, Anti-static device, as mentioned in Valves Handbook, is used to reduce the static charge generated on the ball due to friction. It is used to protect the valve against spark that may ignite the fuel flowing through the valve. My question is: How to test that the anti-static...

    Limit Switches on Compressor Bleed Valve

    We had a problem with the bleed valve twice before during shut-down. During turbine shut-down, the bleed valve should be opened when the turbine speed reaches 95% (14HS - Operating Speed). The problem was that the mechanism that pushes the limit switch didn't fully reach out. The bleed valve...

    IGV Control Trouble Trip

    Dear CSA, Thanks a lot for your help. I apologize for replying late. We did replace the Gas Fuel Servo Valve after that and the turbine is working fine since then. I think oil varnish in the Fuel Gas Servo was the main cause for fluctuations in the fuel gas pressure. It made the IGV servo...

    MARK II to MARK VI Upgrade: Queries

    Are you sure that the number of exhaust T/Cs are up to the customer? The turbine control system does not require a minimum number of exhaust T/Cs? Is the instrumentation of the turbine totally left to the customer requirements and control system engineer commissioning the turbine, or there are...
