Which component is used to motor the Gas Turbine Generator (GTG) for maintenance purposes?

• A. Compressor
• B. Starter
• C. Rotor
• D. Fuel pump

Answer: (B)

The component used to motor the Gas Turbine Generator (GTG) for maintenance purposes is the starter. The starter is specifically designed to provide the initial rotational force needed to begin the operation of the gas turbine. During maintenance, the starter can be used to turn the turbine without ignition, allowing technicians to inspect or service various parts of the turbine safely. In typical operation, the starter engages to get the rotation of the turbine to the necessary speed for ignition and operation. This makes it essential for ensuring that the gas turbine can be tested and maintained effectively without the risk of starting the combustion process. Therefore, the starter's functionality aligns directly with the maintenance needs of the gas turbine, allowing it to be motor-driven without fuel or combustion involvement.
