Determine the system fault kVA and the fault currents at the 415 V and 110 V busbars for short circuit faults on the transformer input or output terminals. Work in p.u. values of impedances.
Below is the diagram of a simple AC generator (image courtesy of http://www.ac-motors.us): There are 4 main parts of a simple AC generator: the magnet, the coil made of electric conducting material, the slip rings and the carbon brushes.
113364 Sequence generator circuit using JKs. Sequence generator circuit using JKs. Please see attached file. JK Flip flops switch their state when J=K=1, and in this case when the clock pulse falls from "1" to "0".
30642 Phasor Diagram for Synchronous Generator Phasor Diagram for Synchronous Generator Solution: Given that the generator is 24kV and Y-connected, we have the rated voltage per phase U = 24/1.732 = 13.86 kV Operating phase A to neutral voltage
An RL circuit consists of a resistor R = 63 ohms, an inductor, L = 45 mH, and an ac generator with an rms voltage of 120 V. (a) At what frequency will the rms current in this circuit be 1.5 A?
frequency, f = Emax/(2πNBA) = 180/(75/280) = 672Hz Power = (Voltage x Current) = [Voltage x (Voltage/Resistance)] (Since from Ohm's Law, Voltage = Resistance x Current, so, Current = Voltage / Resistance) Therefore, P= V2/R For the given circuit
Vs is the output voltage at the generator and Vcustomer is the voltage at customer end. Now, we know that Vcustomer=10 kV and Pcustomer=100k watts. Since p=V*I, therefore, current I in this circuit is 100000/10000=10(A).
145861 Explaining the Meaning of a Simple Circuit Diagram Explaining the Meaning of a Simple Circuit Diagram The top diagram shows a gate (or component) that has three inputs. Two of the inputs are fed by A and the third by B.
A sine wave generator of know amplitude and frequency replaces the battery and the RMS current that flows and the power dissipated is deduced.
