In this post we are providing you an overview of Classification of Lightning Protection Systems (LPS). Lightning Protection Systems (LPS) are categorized into four classes (I, II, III, and IV). This classification is based on the level of lightning protection required. These classes are defined in IEC 62305 (Protection Against Lightning). The higher the class…

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…

Role of Synchronous Condensers in Modern Power Systems (2025)
As power systems around the world transition to renewable energy sources, grid stability has become one of the biggest challenges. Traditional generators provided inertia, reactive power support, and fault current contribution. With renewables like solar PV and wind (which use power electronics), these services are reduced. That’s where synchronous condensers come into play—an old technology…
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…

Inside a 380kV BSP: Overall Layout Drawing Explained
In today’s rapidly growing power networks, Bulk Supply Points (BSPs) play a vital role in ensuring reliable electricity transmission and distribution. A BSP is essentially the bridge between high-voltage transmission lines (380kV in Saudi Arabia) and the sub-transmission network (132kV) that feeds urban centers and industrial zones. While single-line diagrams (SLDs) show the electrical connections,…
