Publication Stray voltage in the dairy barn - Fedagrim

A milking apparatus contains numerous electrical devices and therefore electrical conductors. In perfect conditions, only current flows through these insulated conductors. In reality, a (small) stray current can never be ruled out, which can run along the conductive parts of the barn, such as grillwork.

Stray voltage

Barns are full of metal parts. If these are not grounded properly, a voltage difference can occur between different objects. If the cow touches two such parts simultaneously (e.g., the fence and a drinking trough), or if the cow acts as a grounding device (contact between the fence and the ground), an electric current will flow through the cow's body. Once the current on a metal part is large enough that it flows through the animal to another metal part or to the floor, this is called stray current. These stray currents must, of course, be avoided.
