The solution wasn't complex. It was elegant. He didn't need to redesign the system; he just needed to swap two wires in the marshalling box. The ghost voltage was a feedback loop caused by improper grounding of the DC supply. : Engineering aspects of EHV-AC and HVDC substations,
"Check the auxiliary supply polarity before commissioning," Arjun read aloud. "It is often the smallest wire that trips the largest breaker." : Engineering aspects of EHV-AC and HVDC substations,
