Line Arresters Mitigate Ground Potential Rise on Towers & Improve Electricity Quality
There are two basic technologies for line arresters: non-gapped line arresters (NGLAs) and externally-gapped line arresters (EGLAs) – defined in IEC standard 60099-8. NGLAs are similar to substation arresters, both in design and operation. The main challenge is installation on towers, especially the arrester’s ground connection and its associated disconnector.
