An electrostatic induction spray charging system as attachment to powered knapsack mistblower was developed and evaluated for the performance. A high voltage generator was fabricated on the basis of Cockcroft-Walton voltage multiplier principle with input of 6 V DC battery to provide high voltage required at the developed charging electrode assembly (Model-I and II) for inducing electrostatic charge on spray droplets. | Electrostatic conversion kit for conventional knapsack mist-blower: Development and performance evaluation
