Stray voltage, defined as the voltage between any two animal contacts, can cause
serious problems for livestock, in particular dairy. Dairymen are losing milk production
and are experiencing cow behavior and health problems due to small electrical
currents passing through the cows bodies. The voltages are known by several names,
including neutral-to-earth (N-E) voltage, neutral-to-ground voltage, tingle voltage, and
extraneous voltage. The problem stems from a voltage at an undesirable level between
two animal contact points.
