The electrical power to a meggar is provided by________________?
Correct answer: B. permanent magnet D.C. generator
- A. battery
- B. permanent magnet D.C. generator
- C. AC. generator
- D. any of the above
Explanation
A conventional hand-driven megger uses a permanent-magnet DC generator to produce its test voltage, avoiding dependence on an external supply. Battery-operated versions exist, but they are not the standard answer for this instrument.
