How to Specify the Optimum Non-Gapped Line Arresters (NGLA) ?
What are the necessary system parameters needed to install line surge arresters successfully, not only tower and line insulator data but also other important parameters are presented. The NGLA is then selected from this data and it’s coordinated with the disconnector. The data and simulation software allows you to optimise the installation in order to reduce the line tripping.
Lightning is still the major cause of line tripping disturbances around the world. There are different solutions to reduce this, improving the tower footing impulse resistance, change to underground cable systems or installing line surge arresters, LSA. Installation of LSA’s along a transmission line is often the most economic and easiest solution, as underground cable systems are every expensive and reducing the tower footing resistance is also expensive especially in mountainous regions.
