System and method of capacitance control

A system of an agricultural vehicle and a connected implement, wherein the vehicle and the implement each have a plurality of electric drives wherein each drive is electrically connected to a common connection of the system and electrically connectable to a direct current supply of the system, and having an associated Y capacitor between a connection to the direct current supply and the common connection, the system further comprising an electronic controller and a data store holding a threshold value, wherein the controller is configured to receive capacitance values from each of the electric drives, sum the received capacitance values, compare the sum with the threshold value and, when the threshold value is exceeded, perform a predetermined action,

• wherein the predetermined action comprises performing a predetermined sequence of selectively disconnecting individual electric drives from the direct current supply until the sum of the received capacitance values is less than or equal to the threshold value,
• wherein the system further comprising one or more further electric drives electrically connected to the common connection and the direct current supply, wherein each further electric drive has an associated Y capacitor connectable between the direct current supply and the common connection, and the controller is further configured to selectively connect or disconnect the Y capacitor from the common connection.
