Answer / rishit
Sorry to say but KW-HR is not a unit of electricity
it is the unit by which electricity department charges our
bill the reason after that is if we put a load of 1 kw on
meter then it takes one hour to change its one reading after
one hour
remember i am asking to put only load of one KW not more
than that and after one hour only 1 KW reading will increase
that is why it is KW per Hour

Answer / rajesh
If you want to represent bulk power, you can use a bigger
unit like Megawatt hour or Gegawatt hour. (1 MWH = 1000
KWH; 1 GWH = 1000MWH).

Answer / anil bhatia
the energy meter which measure unit is desine to calculate
kwh . ie 1000 X wattes x Hrs (time consumed or used the
power).
where watts is volts X current .
voltage= is applied/given volts,
current=Amper taken by load

Answer / thuranga
Rishit's answer is also correct,
and also the another one is load is not constant for a
minute in our normal life i.e if we measure power at
12noon,that load will not be same at 12:30 pm.
So on an average the load is calculated on hourly basis for
the purpose of finding the efficiency for all day.,and also
the power consumed domestically.

E.B sending end to receiving end 33kv ug cable laid 8Km,receiving end to ss1,ss2,ss3,ss4 all are Approx 800 Mtr,can go for 33KV to 430V or 33kv to 11kv in receiving end and 11kv to 430 near ss ,which one is good for technically and economically.
