Abstract
A transformer arrangement is disclosed for an electrostatic sprayer or in an adjacent moving element of a coating machine. A transformer provides a galvanic isolation between the line arrangement provided for supplying power to the sprayer arrangement, and consumers at high voltage in the sprayer or possibly in the robot arm. This isolation may be provided with an isolating transformer which has a sufficient isolation distance or other isolation device between the primary and secondary circuits.
