The electrostatic system in nonmetallic units is basically a series of electrical units which are used to specify amounts of electrical charge, current, and volts of electrical power within the meterimeter’s centimeter-to-gram meter scale. In electrostatic units electrical charge is defined as the quantity which it displaces from the surrounding medium. Basically this means that when there is an exchange of charge in the electrostatic system it is called electrostatic attraction. Any charge that will displace will have an opposite charge that is described by a varying charge formula. This formula is usually called EGC or the electrostatic discharge value. It is important to take note that a lower EGC does not necessarily indicate a lower value of the electronic charge.
In most cases, the electrostatic system is composed of a number of individual elements, including a diaphragm or chamber, the base of the meter, a number of grounded conductors, a ground source of low voltage electricity, and an air source of high voltage electricity. The total output will be greater than the input voltage because of the energy dissipation involved in the process. If a large number of grounded conductors are included in the system then the total output may reach hundreds of volts. To keep your Electrostatic system working effectively, you must ensure that all the components have been properly placed.
Before performing any of the maintenance or servicing on Electrostatic systems, you must ensure that you are not holding any grounded object close to the grounded object. For this reason, you should always wear protective gloves and eye protection while handling or working with the Electrostatic system elements. Some of the common maintenance tasks associated with Electrostatic systems include:
Repairing or replacing the resistive elements in the Electrostatic system can be performed by removing the grounding conductor first. Then remove the high voltage power supply lead and short the lead from the power wire to the lead protector. Now, strip the insulation back from the lead and the ground wire with the knife so as to expose the metallic layer. Once done, place a piece of paper between the lead and the steel ground. You should make sure you do not touch the metal surface with your bare hands or any sharp pointed objects.
Many people find that the installation of the Electrostatic system is easier if it has been designed with a touch-free feature. A touch-free device allows you to conduct the installation without touching the metal surfaces. To connect this type of system to the electric supply or to the electric panel, you need to use a small contact charging system. This system is very similar to touchless system and is available in different types including: automatic contact charging, manual contact charging, and hybrid contact charging.
The other type of Electrostatic system is the Friction Based Induction Charging system. As the name implies, the Friction Based Induction Charging is based on the induction charging system which was used a long time ago to discharge metallic particles. The system works on the principle of induced heating between the metallic object and the conducting material. In this method, the energy distribution in the panel is not the same and the electrical charges are induced from a high voltage alternating current passing through the metal object.
The final Electrostatic method is the Friction Based Corona Purification (FPC). This system uses a thin metallic film to protect the wire from the induced electric field. Instead of inducing heating, the current only conducts through the thin layer. The most common use for the FPC is the process of electroplating where a thin layer of metallic coating is used between two Electrostatic devices and afterwards, the charge is induced through the coating.
There are many different electrostatic control devices and their basic function is to draw back (retain) the charged particles so that they do not affect the performance of the device. Some examples of such devices are ventilators, insulators, wrap-around resistors, absorbers, air curtains, spacer pads, tapered versions of the above mentioned components, screen binders and so on. These are the various types of electrostatic control devices and their basic functionality can be illustrated by illustrations like the one below:
