A ground-detection system on an ungrounded shipboard distribution system warns that:
- AThe voltage is too high
- BOne line has developed a ground fault (a second ground would cause a short)✓ Correct
- CThe frequency has dropped
- DThe generator is overloaded
Explanation
Ships often use ungrounded systems so a single ground fault does not trip power. Ground lamps/meters warn of the first ground so it can be found and cleared before a second ground causes a short.
