Abstract
Assumptions concerning span length and termination procedures in fault current testing of optical ground wires are examined. Peak component temperatures were measured for both 10 m and 60 m spans. The cable temperature decay time was measured and is compared with a numerical model of convection and conduction losses. A numerical model is developed to predict the peak cable tension following a hit. This model can be used to establish appropriate initial cable tensions to simulate full-span faults. The issue of dynamic stresses in the form of cable whipping is reviewed. Various cable termination procedures were tested.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
