|Why we called L-G fault as line to ground fault why ground?
suppose if a line falls on building roof then can we called
these fault as line to roof fault? please explain why
ground term is used here?
|why need of ac exietation in alternater.
|why are we using multiples of 11 in substation.
|what is the formula for backup time of online ups?
|What do you mean by reverse current braking of an induction
|what is the exact direction of current?
as we know current travels from higher potential to lower
potential,so if we take battery +ve to -ve implies current
direction is from positive terminal to negative
terminal.,whereas electrons flow from negative to positive
as they are attracted by positive ions.current will be the
plow of charge but not flow of positive ions.please clarify
my doubt friends.
|what is trip circuit supervision relay? How does it work in
|what is the problem in manufacturing transformer with 0
degree phase displacement.???why alwasys go for DYn11 or
DY5?Whys not DY0 i.e zero degree displacement between
primary and secondary side vectors?
|if 11 lead acid batteries each 200 amph are connected in
series so that combinly they can produce 110 volts dc.
question is how much backup it can provide ?
2) how can we calculate that how much amprere and voltage
is required to charge them .
thanks in advance !
