Under voltage is nothing but voltage drop than its rated
level. when the load connected to system varies i.e
increase in sudden load & unbalanced load will cause under
voltage.

Answer / minu

i had asked for the causes of under-voltage, not its
effects.

Answer / amit srivastava

yes there are so many problems will raised on bus bar
first of all it increase the current which will creates
losses in transmission line nd other thing it makes poor
power factor which make transmission conductor less
efficient
as for as bar is concern it will decrese the flux of the
generator so it will creats severe problem to the alternator

can some one clearly explain why -48 volt DC use in telecom site????

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
