Abstract
Tests have been made of the short-circuit stresses on 145 kV busbar systems with flexible conductors. The influence of different parameters has been studied such as span length, sag, conductor type, conductor spacing, spring effect in towers etc. Currents of 20-50 kArmsand short-circuit times 0,1-0,5 s have been studied. The results have been compared with results from manual and computer calculations.Keywords
