For an unbalanced fault with paths for zero sequence currents, at the point of fault
- A. the negative & zero sequence voltages are minimum
- B. the negative sequence voltage in maximum & zero sequence voltage is minimum
- C. the negative sequence voltage in minimum & zero sequence voltage is maximum
- D. the negative & zero sequence voltages are maximum
Answer: D. the negative & zero sequence voltages are maximum
Explanation: At the fault point, the fault acts as the source of negative and zero sequence currents; hence negative and zero sequence voltages are maximum at the fault point and decrease towards the source/neutral.
