hi there. can anybody advise with this one please? a short 3 phase 11kv line delivers a load of 4.1 mw,2.6 mvar lag if the series impedance of the line is (7.2 +j12.1 ) calculate the sending end voltage and load angle. the thing which is confusing me is the 2.6mvar lag bit,i know i...

hi there. looking at the notes i have B is the phase change co-efficent and its in radians.thanks for advice about appropriate symbols, shall look at that.

Homework Statement a transmission line has a length l of 0.4lambda. find the phase change Bl that occurs down the line. Homework Equations B x lambda= 2pi The Attempt at a Solution now here is my problem i am genuinely not sure where to go with this.i don't want this answered for...

Hello mark,many thanks for your words of encouragement. So we are clear, I am not knowledgeable about the functions of logs,natural or otherwise,the exponential function and Ln function are also difficult to understand. When i am saying "i do not understand" it is actually because i don't...

Re hallsofivy... to be honest feel I'm getting a lot of hostility here, i asked for help with an equation i did'nt understand, i don't need a not a lot of smart comments, what's this all about? if you can't help without belittling me don't bother really its not worth the hassle.

mark suspect i irritated you there. i do not want you answer the question for me,that is up to me.i am just not understanding it.

apologies mark.you have lost me there,think you see my problem, where did b and a come from!

hello mark,thankyou for assisting me,inverse of the Ln function is the "e" function but adding -3 will get rid of the +3 on the Lhs but how does this help as its now -3 on the rhs!

ok,i see where you are going with this! how do i transform the equation to "y" only,especially with the "In" ? suspect i need to multiply the brackets through by the "In" function which will then simplify it? hmn,not sure, this is confusing again,"y" is top and bottom! or should I put in the...

hi there obviously i need to transform this equation for y?

help req/d please not getting this! hi guys can someone assist with this one please before i pull any more hair out. the age of a machine,x, in years is related to the probability of breakdown,y, by the formula x=3 + In( y/1-y) determine the probability of breakdown for 1,3,10 years...
