The first interrupter is electrically coupled in parallel with the bypass switch. A making switch causes a cancellation current to flow from an energy source through the second interrupter, and through the first interrupter, in addition to the DC current. The AC high voltage breaker is adapted to a DC service as the DC current in addition to the cancellation current causes an arc quench which allows the AC high voltage breaker to cause the interruption of the DC current in the electrical circuit. A method for interrupting a DC current flowing in an AC high voltage circuit breaker is also described."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method to interrupt a DC current in a high voltage circuit by use of an AC circuit breaker","description":"An electrical circuit to interrupt a DC current includes a bypass switch and an AC high voltage breaker which includes interrupters that are rated for carrying a current having a value of the DC curre","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9608431","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.
