Arc Properties

Arc Properties: The manner in which the are medium is made to conduct has already been studied. A plot of instantaneous values of voltage eB between the electrodes of a burning arc against the corresponding values of current gives the Arc Properties. With the increase of arc current the temperature rises and the process of ionization […]

Differential Protection Relay in Power System

Differential Protection Relay in Power System: A Differential Protection Relay in Power System scheme compares quantities derived from the input and output currents of the protected circuit in such a manner that, for all healthy system and through fault conditions, the quantities balance and the protection is inoperative, while for internal fault conditions the balance […]
