ABSTRACT:
A central milking system with electrical units energized by an a.c. voltage source having an earth grounded neutral conductor. Stray current inherently produced in the neutral conductor by neutral-to-earth voltage is prevented from being conducted to the teats of the cow being milked via the flow of milk from the cow by creating a highly electric-insulating path between all bodies or films of milk which extend to the cow and all conductive components which are connected to the neutral conductor.
