What is stray voltage?
Stray voltage is caused when a power line’s neutral line is “leaking” electrical currents into the ground. A common cause of stray voltage is a neutral wire that is either too small or damaged and allows the current to go into the ground. Even when the stray voltage current is at a low level, specifically anything above 0.5 volt, it can still be harmful to livestock.
