🔍 Key Concepts

• Ignition systems on gas turbine engines typically use a transformer to step up voltage from ship’s power to a much higher secondary voltage at the igniter plug. • Compare the voltage ranges of typical ship service power (115/440 VAC) to the much higher voltages needed to jump an air gap in a high-pressure combustor. • Think about how the required spark intensity in a gas turbine combustor compares to that of a gasoline engine spark plug (often around 20,000–40,000 volts).

💭 Think About

• Which of the answer ranges looks like normal shipboard supply voltage, and which look like transformed, high-voltage ignition output? • To reliably jump an air gap in a high-pressure, high-velocity airflow inside the combustor, would you expect a relatively low voltage or a very high voltage at the igniter? • Among the high-voltage options, which range seems more realistic for a durable marine ignition system that must fire repeatedly without destroying the igniter?.

✅ Before You Answer

• Eliminate any options that match standard ship service power (115 or 440 VAC), since the question asks for secondary voltage at the igniter, not supply voltage. • Focus on the options that represent a stepped‑up ignition voltage capable of producing a strong arc in the combustor. • Before choosing, ask whether the voltage is so extremely high that it would likely cause rapid erosion or breakdown of the igniter instead of reliable service.
