Hello students.
00:01
Today we will discuss about this question.
00:03
In this question we are given that a generator with a sequence reactance, that is, reactance, that is equals to 0 .2 p .u is grounded through a reactance of 0 .05 p .u.
00:22
It supplies a motor through a transformer and zero sequence reactance of motor, that is 0 .3 p .u and its natural solidity grounded, and the leakage reactance of the transformer.
00:39
So here, leakage reactance, that is equals to 0 .1 p .u.
00:46
So here, first of all, we need to draw the zero sequence network.
00:51
So here we need to draw zero sequence network.
00:58
Network and after that we need to find we need to find for the following construction that it's first is star grounded delta second one is delta delta so here first of all for the first one here it is a here it is m so here x g that is equal to j 0 .2 xt that is equals to j 0 .1 and xm that is equal to 0 .3.
01:48
And here it is star grounded.
01:51
And here, star j 0 .05.
01:59
Now, this will be the answer for the first that is zero sequence network.
02:04
Now, for the second, that is part for the part a, that is star grounded...
