التقدير الحراري في الوقت الحقيقي (RTTR)
يعمل RTTR (التقدير الحراري في الوقت الحقيقي) أو DCR (تقدير الكابلات الديناميكية) على حساب درجة حرارة الموصلات باستمرار من خلال أخذ الحمل الحالي والحمل التاريخي والظروف الحرارية وغير ذلك من العوامل في الاعتبار. وفي نفس الوقت، فإنه يتنبأ بالحد الأقصى للحمل المسموح به للحالات الثابتة وحالات الطوارئ. بناءً على معايير الصناعة IEC 60287 وIEC 60853 ونماذج العناصر المحدودة، يمكنك تشغيل الشبكة بأعلى مستويات التيار الآمن الممكنة مع إمكانيات توقع ممتازة. ويعتمد حساب RTTR على النماذج الحرارية الدقيقة التي تعكس حالة التربة / الجو المحيط على طول كابل الطاقة عالي الجهد.
لقد تعاونا معًا لسنوات مع الشركة الرائدة في السوق تقييم البرامج للوصول إلى بيانات دقيقة وموثوقة. يتم دمج نتائج التقييم بالكامل في منصة برنامج SmartVision من AP Sensing ويتم عرضه بسهولة في مركز إرسال أحمال المشغلين عبر بروتوكولات قياسية مثل Modbus TCP أو IEC 61850 أو IEC 60870-104 أو DNP3 أو OPC.

115kV Underground Power Cable Saudi Arabia June 2020
Khudriyah-2 BSP is a new grid station situated on the outskirts of Dammam city, Kingdom of Saudi Arabia. Our Distributed Temperature Sensing (DTS) system was deployed to monitor the temperatures of two 115 kV underground circuits, providing thermal profiling and insights into the the actual conductor temperature and transient statuses with Real Time Thermal Rating (RTTR).
Underground Transmission Cable Monitoring Pakistan May 2020
AP Sensing is monitoring a 132 kV underground transmission cable for Karachi Electric. This cable experiences greater loads than nominal lines, as it feeds energy to a steel mill with high energy throughputs and frequent consumption cycles. Our solution provides end-to-end temperature monitoring to reduce thermal overload and cable faults. Additionally, RTTR and our asset viewer software enhance operational insight.
Underground Power Cable Utilizing DAS March 2020
An AP Sensing Distributed Acoustic Sensing (DAS) system is monitoring a 6 km high-voltage power cable in Germany. A key feature of DAS is the ability to immediately detect and locate cable faults. This helps optimize transmission and distribution networks, and reduces costly and unnecessary operational costs and asset downtime.
