We all have seen transmission and Distribution lines In
transmission lines the voltage is high and current is low(to
reduce I^2r loss) and in distribution lines voltage is low
but current is high however the size of transmission wires
is bigger than that of distribution wires even though the
amount of current carried by the distribution lines is more
than that of transmission lines why?

Answer Posted / murali290

In transmission the power carried is very high compared to
distribution.even low currents in transmission means it is
of range Kilo Amps ,inorder to carrying that much high
power(VI).
where as in distribution low power is carrying .even though
high currents means not that much as in transmission.hence
small conductors are present in distribution compared to
transmission

Hi Suppose we have a wye/wye transformer which is grounded at both sides,in this situation, do we have ay ground transformer? in other words, ground transformer can do any thing more (while we have nuetral wire in both sides)? As the last question, what about 3rd harmonic? we have two choices: first using wye/delta transformer + ground transformer and second using wye/wye earthed connection.in the former choice, we dont have 3rd harmoonic at the secondary side but what about Yn/yn conection? do we suffer from 3rd harmonic in the Yn/yn connection?

if there are six generators (3 gas CATT, one Jenbacher o1 MW each, and two nos Diesel 01 no 01 mw other 0.65mw EDGs ( say), 3 CAtt gas set have identical pole pitch,01mw EDG and Jenbacher gas Set have different pole pitch, how their power connection can be done to connect a common bus bar during installation. in short, how different pole pitched generators power connection can be done to connect a common busbar system through generators incomer ACBs.

I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
