1. Introduction Electric power transmission is the lifeline of modern civilization. As electricity demand continues to grow, countries around the world are focusing on transmitting large amounts of power over long distances with minimum loss and maximum reliability. High Voltage Alternating Current (HVAC) and High Voltage Direct Current (HVDC) systems are two advanced technologies that […]
Ground clearance is the vertical distance between the lowest point of a transmission line conductor and the surface of the ground directly below it.It ensures public safety, prevents electrical flashovers, allows for vehicle and equipment movement, and provides sufficient space for maintenance activities. In 380 kV Overhead Transmission Line (OHTL) design, especially in Saudi Arabia
What Ground Clearance Is and Why It’s Important in Overhead Transmission Lines? Read More »
🔹 Introduction Across the deserts and mountains of the Middle East, thousands of high-voltage towers stand tall, carrying electricity over hundreds of kilometers.But the true safety and reliability of these lines lie underground — in the grounding system. Grounding (or earthing) in Overhead Transmission Lines (OHTL) provides a safe, low-resistance path for lightning strikes and
Introduction File management is one of the most overlooked yet critical skills in PLS-CADD. Every model you create—terrain, structures, cables, or design criteria—relies on linked data files.If one file goes missing or is overwritten, your entire project can break. In this article, you’ll learn how to save, back up, restore, and organize your PLS-CADD projects
