Question 1 of 27070

Which of the following represents a characteristic of an ungrounded electrical distribution system?

🔍 Key Concepts

• Ungrounded electrical distribution system behavior during a single line-to-ground fault • Difference between single ground fault and double ground fault conditions • Purpose of ground detection systems on ungrounded systems

💭 Think About

• Think about what happens if only one conductor in an ungrounded system accidentally touches ground—does current have a complete path, or can the system keep operating? • Consider why ships with ungrounded systems often install ground detectors. If ground detection were unnecessary, what would that imply about safety and fault finding? • Compare which situation is more dangerous for an ungrounded system: one line to ground, or two different phases both faulted to ground.

✅ Before You Answer

• Verify what the primary safety advantage of an ungrounded system is with respect to a single ground fault. • Confirm whether double ground faults on different phases can create a normal current path between phases (and what that would do to the system). • Check whether regulations and good engineering practice call for ground detection on ungrounded systems, or say it is unnecessary.

Question 1 of 27070

Which of the following represents a characteristic of an ungrounded electrical distribution system?

Accidental contact between one line and ground does not cause an outage.

Double ground faults on different phases will not cause an outage.

Ground detection systems are unnecessary.

Accidental contact between one line and ground will always cause an outage.
