🔍 Key Concepts

• Purpose of using a megger (megohmmeter) on electrical equipment • Why insulation quality is critical on tank vessels, especially around flammable cargoes • Difference between measuring insulation condition vs. normal operating electrical characteristics

💭 Think About

• Ask yourself: What quantity does a megger actually measure—voltage, current, or resistance—and between which points? • Which of these choices is directly related to preventing leakage currents and arcing to ground on a motor? • Which options describe phenomena or properties usually analyzed in design/calculations rather than in routine safety maintenance tests?

✅ Before You Answer

• Identify which option refers to resistance between windings and the motor frame/ground. • Eliminate options that are more about electromagnetic effects during operation than about safety checks at rest. • Focus on what is most important on tank vessels with flammable atmospheres: preventing breakdown of electrical insulation.
