Artificial Intelligence Applications in Transmission Line Design
Artificial Intelligence (AI) is rapidly transforming the power transmission industry by improving design accuracy, reducing engineering time, minimizing costs, and enhancing asset reliability. In modern transmission projects, particularly large-scale projects in Saudi Arabia such as 380kV and HVDC networks, AI is becoming an essential engineering tool rather than a futuristic concept. Artificial Intelligence (AI) fundamentally…
Technical Strategies to Improve Transmission Line Efficiency
In modern power systems, the efficiency of transmission lines directly affects overall grid performance, operating costs, and reliability. Since transmission losses primarily occur due to conductor resistance and reactive power flow, engineers must carefully evaluate both design and operational strategies to minimize these losses. Below is a detailed technical review of methods to improve transmission…
SEC Standards Update: New vs Old
Saudi Electricity Company (SEC) has issued new standards that mayl soon replace the old ones. These updated codes are essential for engineers, consultants, and contractors working on substations, OHTL (Overhead Transmission Lines), and power system projects in Saudi Arabia. Key Points to Remember: Our Most Read Posts In the old SEC standards, the first letter…
Sag templates & Curves
Sag templates are a critical tool in the design and construction of transmission lines. We usually use these to determine the vertical position of conductors (and ground wires) under specified design conditions, ensuring that the transmission line provides adequate clearance to the ground and other facilities. Below is a detailed explanation of sag templates based…
