cameroon gce 2023 intermediate level Electrical and Electronic Circuits 2
A three phase four wire supply of 550V, 50Hz star connected circuit has impedances connected to it as
follows:
Red phase: A resistance of 10£2 in series with an inductance of 0.047H
Yellow phase: A resistance of 250
Blue phase: A resistance of 30Qbin series with a capacitor of 63.6pF.
a) Draw the diagram of the circuit
b) Calculate the inductive reactance and the capacitive reactance in the red and blue phases respectively
c) Calculate the impedance in each line
d) Calculate the current in each line
e) Calculate the current in the neutral conductor
