That consists of a significant metal ball mounted on high insulating facilitates. An endless belt b, made of insulating material such as rubberized, passes over the vertical pulleys P1 and P2. The pulley P2 is at the centre in the metal sphere and the pulley P1 can be vertically under P2. The belt is definitely run by simply an electric engine M. B1and B2 happen to be two material brushes referred to as collecting combs. The positive fatal of a substantial tension source (HT) can be connected to the comb B1. As a result of process known as action of points, charges are accumulated at the indicated ends from the comb, the field improves and ionizes the air close to them. The positive charges in air are repelled and get transferred on the seatbelt due to corona discharge. The fees are transported by the belt upwards as it moves. When the positively billed portion of the belt will come in front in the brush B2, by the same process of action of items and reino discharge takes place and the metallic sphere acquires positive fees. The positive fees are consistently distributed within the surface with the sphere. As a result of action of points by the negative expenses carried by gas in front of the comb B2, the positive fee of the seatbelt is neutralized. The uncharged portion of the belt earnings down collects the positive impose from B1 which in turn can be collected by B2. The charge copy process is usually repeated. As increasing numbers of positive expenses are imparted to the ball, its confident potential continues rising right up until a surface maximum is reached. In the event the potential includes more than this, insulation property of air reduces and the ball gets discharged. The break down of atmosphere takes place within an enclosed metallic chamber filled with nitrogen for high pressure.
