<p>The invention relates to an electrostatic spraying arrangement for the serial coating of workpieces, wherein the high-voltage sensors (7) and actuators (6) of the sprayer (11) are supplied by an isolating transformer (T1-T3) in the sprayer (11) and/or in a robot arm (10) with a high voltage insulation path. Control and sensor signals for the actuators (6) and sensors (7) are transmitted potential-free, for example, optically or by radio.</p>
