In the formula to calculate QR at the receiving end of the line, I am wondering if the term cos(beta.l) goes in that expression. Since X' was calculated as a concentrated reactance. Thanks.
Thanks for the great presentation, but I have a question. In many references, hyperbolic trigonometric functions are used to represent the generalized model of a transmission line. Why are you using basic trigonometric functions (sine cosine).
thank you sir for this very clear explanation, and I asking if you have lectures for Distance protection? thank you again
Will upload soon.
@@DebunkingPowerEngineeringThank you sir

What does it mean????
Why do we consider Ia and Va as at UPF at the beginning of the analysis instead of considering Ia lag Va just as in real condition?
yes we can consider this scenario as well, but the condition of UPF is used to make the lecture easier to understand. The case that you are talking about is considered in the next lecture in which the 30 and 90 degree connections are considered.
Pranam sir 🙏 my name is asutosh are u teach flexible ac transmission system topic.plese sir can u help me in this topic
Yes I will teach the FACTS devices in the latter lectures.
What is SIL ?
SIL is surge impedance loading. To have more insight about SIL kindly go through the following lecture: th-cam.com/video/51ocqAw0Z4w/w-d-xo.html
great explanation 👌🏻 but I have one question why did you put the torque at point p while it's at the point O
In the starting of this section it was mentioned that the horizontal component of the tension is constant through out the conductor. So whatever is the tension at point O is the tension at the point P. That's why.
Sir send me your e mail address please
