This paper presents a simple method to minimize lightning surges entering an uprated or compact substation. A severe lightnmg stress is caused by a backllashover in close proximity to the substation. Feasibility of uprating is based on the surge arrester technology available at present. However, some aspects of line design offer opportunities in reducing Gequency and seven@ of lightrwg surges imposed on the substation. The tower surge response adds an inductive 'overshoot' only during the front of' the stroke…
