Lining up their feet with the >equipotential lines in the soil could caused by this effect ! Yes, cows are very sensitive to electricity. 25 V from end to end (excluding tail) has proved fatal. However, the ground currents due to overhead lines should not produce significant voltage drops. There is, or should be, a bonding conductor connecting the tops of consecutive towers. -- OOO - Own Opinions Only. Try www.jmwa.demon.co.uk and www.isce.org.uk Things can always get better.
