Here the given system is three phase overhead system, three phase overhead system, frequency that has been given which is let's suppose we can take it as f and that's equal to 60 hertz.
00:30
In the same way we have the length of the system and let's suppose this is l and that's equal to 230 kilometer.
00:39
Okay this is what we have.
00:41
Next we have i mean the 230 kilometer and next we have the series independence which is let's suppose we can write series independence that is z value and that's equal to 0 .8431 angle of 79 .04 degree and the units are ohm upon kilometer.
01:10
After the shunt admittance that's equal to y and that's equal to 5 .105 multiplied by 10 to the power of minus 6 angle of 99 .8 degree.
01:36
Okay this is what the shunt admittance we have.
01:40
After that we will go load at receiving which is pr, load at receiving that's equal to 125 mw and receiving at okay power factor which is given as okay we have to find out and receiving end voltage which is vj that's equal to 215 kilo volt.
02:05
Now using this okay using this equivalent pi circuit we will go forward to calculate total series independence that's equal to z is equal to z multiplied by l.
02:26
So here z is value has been given that is 0 .8431 angle of 79 .04 degree multiplied by l value which is 230 and from here we will get this value as equal to how much let's keep it z dash okay so we will get here that is 193 .913 angle of 79 .04 degree ohm.
02:57
This is what called the total series independence.
03:00
Now let's go ahead to calculate the total shunt independence i mean admittance...
