AP4 Group – Full-Service Heavy-Duty & Aeroderivative Industrial Gas Turbine Maintenance Provider.

TC&E- A Division of AP4 Group Recommends Scheduling the Following Reliability Assessments:

Clean and Inspect Turbine Control Panels and HMI Computers

Remove dirt and dust that accumulate and can cause paths of current to ground which can lead to premature failure of circuit cards, and hard drives, and cause erroneous and nuisance diagnostic alarms.

Ensure all screw terminals, ribbon cables, and wire connectors are tight and not corroded and coat required connections with nyogel electric grease to prevent corrosion and ensure a good path for signal passing is established.

I&C Calibrations

Efficient gas turbine operations require specific and accurate data from the field devices. If the data received at the control system is not accurate, the system cannot properly calculate firing temperature, fuel scheduling, or MW demand. A 1% error in compressor discharge calculation is equivalent to a 1% loss in turbine output. Calibrations are cheap insurance to ensure your generator is making all the power it is capable of.

Critical Component Calibration Inspection

If the data received at the control system is not accurate, the system cannot properly calculate firing temperature, fuel scheduling, or MW demand. A 1% error in compressor discharge calculation is equivalent to a 1% loss in turbine output. Calibrations are cheap insurance to ensure your generator is making all the power it is capable of.

Servo Replacement Program

Servos are the heart of your critical valves and require maintenance and rebuilding more often than most think. Often servos are not thought of until they fail in service causing missed starts and forced outages. TC&E - A Division of AP4 Group recommends that each site buy a spare set of servos and once a year swap them out and have them sent off for inspection and rebuild. Contact our parts division AP+M - A Division of AP4 Group to learn more about available replacement parts and repair services.
