Abstract

يتعلق الاختراع الحالي بطريقة لاكتشاف خطأ تأريض عالي المعاوقة high-impedance ground fault بشبكة إمداد طاقة كهربائية electrical energy supply network (12) بنقطة تعادل مؤرضة grounded neutral point، حيث يتم تغذية إشارة الاختبار test signal بجهاز كشف detection device (10) بداخل شبكة إمداد الكهرباء (12)، حيث يكون لإشارة الاختبار تردد frequency والذي يختلف عن تردد الشبكة network frequency بشبكة إمداد الكهرباء (12)، ويُستدل على وجود خطأ تأريض عالي المعاوقة على أساس إشارة القياس measuring signal المُنتجة بواسطة إشارة الاختبار. لكي يتم التمكن من إجراء اكتشاف موثوق به، بأقل تكلفة للمعدات المستخدمة، لأخطاء تأريض عالية المعاوقة high-impedance ground faults بشبكات إمداد الطاقة energy supply networks بنقطة تعادل مؤرضة، فإنه يُقترح أن يتم تغذية إشارة اختبار ثلاثية الأطوار إلى داخل موصلات الطور conductors بشبكة إمداد الطاقة (12) كإشارة اختبار، يتم توليد إشارة قياس والتي تُشير إلى جهد الإزاحة لإشارة الاختبار بجهاز كشف (10)، يتم مقارنة جهد الإزاحة بقيمة الحد الأدنى التي تستخدم وسيلة اختبار (15) بجهاز كش
