यदि किसी विद्युत प्रणाली में दोष बिंदु पर सभी अनुक्रम वोल्टेज समान हैं, तो दोष __________ है

Concept & ReasoningFault type determines how sequence networks interconnect. A three-phase balanced fault uses only the positive-sequence network. A line-to-line fault uses positive and negative sequences without zero sequence. A single line-to-ground fault places the three sequence networks in series, producing equal sequence currents. For an LLG fault, the sequence networks have a parallel-type connection at the fault point, making the sequence voltages equal.How to Solve It in the ExamEqual sequence voltages → think LLG parallel sequence-network connection.Important Exam PointMemorize network interconnections, not just fault names.Related Revision PathThis question sits in the revision path Power System → Fault Analysis →…
