A contactor controller opens a first contactor when the load circuit detects the occurrence of the line-to-ground fault, and when a line-to-ground fault location detector detects that a location of the line-to-ground fault is at the power-transmission-circuit side, the contactor controller maintains the open state of the first contactor even if an operation to instruct closing of the first contactor is made after the first contactor is opened."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power converter and power conversion method","description":"A line-to-ground fault location detector detects, based on a difference between a current flowing from a power transmission circuit to a load circuit, and a current flowing from the load circuit to th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9748832","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
