Question

Choose the correct one: The zero sequence voltages are single phase voltages and they give rotating field in ___ space

• A. space
• B. give an alternating field
• C. give an alternating field in space
• D. space

Hint:

Zero sequence components are useful for analyzing unbalanced faults, especially single-line-to-ground faults.

Answer 1

The Correct Option is D

Zero sequence voltages are single-phase components that result in a rotating magnetic field in space under symmetrical fault conditions. They do not contribute to useful power transfer but are important in protection schemes.
