Excerpt from Stray Currents From Electric Railways BY suitable insulation it is always possible to so protect a conductor of electricity that no perceptible leakage to the surrounding medium can take place, even though this medium be a good conductor. However, if it is impossible to so insulate the conductor from the surrounding medium the latter will take part in carrying the current. This is the case when rails are used for the return circuit. A part of the current branches off into the earth, returning again to the rails at certain fixed points. These currents are called stray currents. These stray currents also occur, though to a lesser extent, in three-wire systems with a bare middle conductor, and many times to a greater extent in cables which have bad faults. Faults in cables generally produce only local disturb auces, which in most cases are easily located and quickly remedied. The stray currents in a three-wire system with a bare middle wire may be kept so small, by balancing the loads in such a way as to give a proper current distribution, that no harm can result from them. For this reason in the following discussion the stray currents in electric railway systems will be particularly considered.
