I have a problem solving the folloing assignment question.
I am familiar with the condition in balanced star-connected load but do not no how to star solving unbalanced loads.The convertion to delta is will be straight forward once Q1.1 is solved.I do not know where to start as I have not seen a Example like this in any of our studie books.
The question reads.
An unbalanced,Star connected load is connected to a 380-V,Thee-Phase,Four-wire supply.Take Vnc as the reference Phasor with a positive phase sequence.
The impedances are as follows.
Z an = 7,8 /_35,6 Ohm
Z bn = unknown ?
Z cn = 10,5 /_63.8 Ohm
I n = 24,6 /_ -76 A
1.1 Calculate the value of the impedance in phase b
1.2 Convert the system to an equivalent Delta-connected system.
Can anyone help?
