The inductive reactance is determined using equation 821a. How the electric utility industry generates and delivers power to its customers covering basics, delivery, safety and generation. Learn vocabulary, terms, and more with flashcards, games, and other study tools. The effect of a sinusoidal supply produces a phase difference between the voltage and the current waveforms.
But since reactance is already expressed in the form of ohms in a purely reactive circuit ohms laws applies normally for a purely. Inductive reactance an overview sciencedirect topics. Inductance, capacitance and resistance since resistance doesnt effect phase the net of the two reactances, with the lessor subtracted from the greater, will act upon total impedance at 90 to resistance. The reason for this inductive reactance can be simply seen by examining the selfinductance and its effect within the circuit. L inductance property of circuit where change in electric current through the circuit induces an electromotive force that opposes the change in current increase ac frequency what will be the effect. The effect by which the current flow of an alternating or changing current in an inductor is reduced is called its inductive reactance. Download fulltext pdf download fulltext pdf modelling and simulation of inductive fault current limiters article pdf available in physics procedia 36. Reactance, then, increases with an increase of frequency and with an increase of inductance. The following example problem illustrates the computation of x l. We will also combine the information from a previous video to. Like resistance, reactance it is measured in ohms, but is separate from the opposition to current caused by any internal resistance within the inductor. Pdf modelling and simulation of inductive fault current. Any changing current in an inductor will be impeded as a result of the inductance associated with it. Combined resistance and reactance in practice, most circuits contain a mix of resistive components along with reactive components that could be inductive or capacitive.
Ac inductance and inductive reactance in an ac circuit. Inductive reactance definition of inductive reactance at. In this video we will see what happens to inductive reactance as inductance changes. The inductive reactance of an inductor increases as the frequency across it increases therefore inductive reactance is proportional to frequency x l.
