The secondary side is connected via a rectifier to a filtering capacitor, delivering electrical power to a load. One of the output pins of the filtering capacitor is connected to a secondary ground at the rotating part which is further connected to a stationary protective ground via a galvanic slip ring. In the case of a short circuit between a secondary transformer winding and the secondary ground, the secondary winding is partially short-circuited by one of the rectifier diodes. This causes an asymmetric current load at the primary side and a current flowing through the slip ring. Both currents may be used to detect a failure of the secondary winding."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Inductive rotary joint with secondary safety circuit","description":"An inductive rotating power transfer circuit, preferably for transferring electrical power from the stationary part to the rotating part of a CT scanner comprises an inductive power transformer having","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9649085","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.
