Corona Definition

Circuit Breaker — An automatic device for stopping the flow of current in an electric circuit. Outside this region of ionization and conductivity, the charged particles slowly find their way to an oppositely charged object and are neutralized. Corona: When the potential difference increase in the transmission according to that the also increases. When the potential is large enough at a point in the fluid, the fluid at that point ionizes and it becomes conductive. All of the current in the circuit must flow through all of the loads. Ferroresonance — nonlinear resonance a type of resonance in electric circuits which occurs when a circuit containing a nonlinear inductance is fed from a source that has series capacitance, and the circuit is subjected to a disturbance such as opening of a switch.

This asymmetry is a result of the great difference in mass between electrons and positively charged , with only the having the ability to undergo a significant degree of ionizing at common temperatures and pressures. Capacitance — The ability of a body to store an electrical charge. The parallel capacitor represents the remaining unvoided capacitance of the sample. Relay — An electrical coil switch that uses a small current to control a much larger current. Load Rejection — The condition in which there is a sudden load loss in the system which causes the generating equipment to be over-frequency.

The E-corona E for emission is due to spectral emission lines produced by ions that are present in the coronal plasma; it may be observed in broad or forbidden or hot spectral emission lines and is the main source of information about the corona's composition. If a charged object has a sharp point, the electric field strength around that point will be much higher than elsewhere. When the air near the point becomes conductive, it has the effect of increasing the apparent size of the conductor. The sulfuric acid - water solution in a storage battery is an electrolyte. Diodes allow current to flow when the anode is positive in relation to the cathode.

Since the new conductive region is less sharp, the ionization may not extend past this local region. To restore service, the fuse must be replaced using a similar fuse with the same size and rating after correcting the cause of failure. Therefore, if electrons are to be used in an application which requires high activation energy, positive coronas may support a greater reaction constant than corresponding negative coronas; though the total number of electrons may be lower, the number of very high energy electrons may be higher. In the intermediate region, electrons combine to form negative ions, but typically have insufficient energy to cause avalanche ionization, but remain part of a plasma owing to the different polarities of the species present, and the ability to partake in characteristic plasma reactions. Ohmmeter — An instrument for measuring the resistance in ohms of an electrical circuit. Mechanism of corona discharge Corona discharge results when the electric field is strong enough to create a chain reaction: electrons in the air collide with atoms hard enough to ionize them, creating more electrons which ionize more atoms.

Therefore voltage spikes are generated. Search corona and thousands of other words in English definition and synonym dictionary from Reverso. The difference, then, between positive and negative coronas, in the matter of the generation of secondary electron avalanches, is that in a positive corona they are generated by the gas surrounding the plasma region, the new secondary electrons travelling inward, whereas in a negative corona they are generated by the curved electrode itself, the new secondary electrons travelling outward. Reluctance — The resistance that a magnetic circuit offers to lines of force in a magnetic field. Rectifier — An electrical device that converts an alternating current into a direct one by allowing a current to flow through it in one direction only. The total number of electrons and electron density is much greater than in the corresponding positive corona.

Data collected during the procedure is compared to measurement values of the same cable gathered during the acceptance-test. A further feature of the structure of negative coronas is that as the electrons drift outwards, they encounter neutral molecules and, with such as and , combine to produce negative ions. The free radicals and ions generated in corona reactions can be used to scrub the air of certain noxious products, through chemical reactions, and can be used to produce. Polarity — A collective term applied to the positive + and negative - ends of a magnet or electrical mechanism such as a coil or battery. A positive corona generates much less ozone than the corresponding negative corona, as the reactions which produce ozone are relatively low-energy. Heat energy dissipation may cause thermal degradation of the insulation, although the level is generally low.

Controlled corona discharges are used in a variety of filtration, printing and other processes. The loss is determined by multiplying the current by the voltage. . The usual way of quantifying partial discharge magnitude is in pico. One farad is equal to one coulomb per volt.
