Abstract
A voltage compensation circuit is coupled to a conventional milking system so that when a milk stream flows from a cow to a milk pipeline, a voltage compensation circuit makes contact with the milk stream. As a result, due to the voltage compensation circuit's output voltage, a current that might be generated by the electric potential difference between the cow and the milk pipeline is prevented from flowing within the milk stream. Accordingly, electric shocks to the cow are effectively prevented.
