Van de Graaff Generator
An electrostatic generator which employs a system of conveyor belt and spray points to charge an insulated electrode to a high potential.
- An endless motor-driven dielectric belt runs through the support from the base to the pulley within the terminal.
- In the machine, charge is sprayed by point discharge from metal needles, held at a potential of about 10 kV, on to the bottom of the belt.
- A row of needles near the upper belt pulley removes the charge from the belt and passes it to the outer surface of the spherical terminal.
