Stray voltage

A fallen power conductor from a transmission line forces current through the earth; the resistance of the earth to current produces a voltage difference between the point of contact and distant earth. If the rate of change of voltage with distance is large, a dangerous potential may exist between the feet of a person in the area.

The very small capacitance between overhead lines and a fluorescent lamp tube (in the foreground of the photo) provides enough current to cause the lamp to glow.

Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
