Power should be 3 phase power or single phase power? And viltage will get line viltage or phase voltage?

3:33 How is P / (P + ( Pl(rho)(delta)) / Vcos(phi) ) = 1 - ((rho)(delta)l / Vcos(phi))

First, take P out of the numerator and denominator: P/P = 1. Then you are left with 1 / (1+R), where R is the ratio including the cosine. Then multiply by 1 = (1-R)/(1-R). After expanding this, you are left with (1-R)/(1-R^2). Here is assumed that R is small and R^2 is almost nihil. Then the denominator becomes 1 and you are left this result: 3:24. I just described the simplification. Remember, etha is a number smaller than 1. Sir is a bit hasty in his lectures ;-)

Sir in emperical formula load is in kva or kw. As some books shows in kw

Sir,from ur point of view receiving end must be 10kv,20kv,30kv,60kv,130kv,200kv .Then why did not taken 40kv, 50kv like this. My question is particularly why did taken these ratings And i require information about kv rating with respect to distance & load KVA for each kv rating based on approx empirical formula in table form.

Why voltage taken in the multiple of 11such as 11kv,33kv,66kv,132kv,220kv

Sir, how to download your hand written notes.

Sir , here when you are taking 'W'' as constant , then volume is inversely proportional to square root of voltage.. but sir ' W ' is also depends upon V , then how we can maintain it as constant .

@@lecturesinelectricaleng sir , here W is power loss in line , and in its relationship it directly proportional to current density and inversely to Voltage , current decreases with increasing voltage . for constant W current density must be proportional to Voltage, so I think we can not take current density as constant...

So how we can take W as constant while changing voltage and taking current density as constant
