Calculating Electrostatic Effects of Overhead Transmission Lines

This paper presents an approach to predict ground-level electrostatic effects from overhead power transmission lines using the voltage gradient at ground level. Objects like vehicles and animals are represented by Norton equivalent networks. The advantages in using this method are 1) accuracy in predicting induced short-circuit current, ¿sc, open-circuit voltage, ¿oc, and capacitance of object to ground, Cog, and 2) simplicity in needing only simple slide-rule computations that are practical in the field.
