Abstract
An electrostatic spray system has a support for a liquid container, and the high voltage components mounted through isolators for providing electrical insulation relative to a low voltage or grounded support. The liquid container is connected to a pump that provides the liquid under pressure, after an electric charge is applied to the liquid on the exterior of the liquid container. The liquid container has an open top, and a sprinkler head adds liquid to the liquid container. The sprinkler head is mounted on the low voltage support, but all high voltage components are electrically isolated from low voltage components to insure there is little current leakage back to ground.
