The system includes a differential current electromagnetic sensor having a magnetic core with a center region that the power cable passes through one or more times. The magnetic core has an air gap in which a magnetic flux sensing device is positioned and configured to provide a signal that is representative of magnetic flux across the air gap, which is indicative of a difference between the inlet current and the outlet current. This difference defines the leakage current."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Differential leakage current measurement for heater health monitoring","description":"A system and method for monitoring leakage current in a heater connected to a heater power supply by a power cable having a first power lead conducting an inlet current defining an inlet current direc","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11293995","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.
