Answer / natha

on the basis of load curve it is calculated.if suppose you have to find the max demand(md)of ur house plot time on x axis units consumed on y axis.you get supppose 2units 6am 30 7am 42 8am 5 9am.....till midnight.then ur max demand is 42units.all other factors such as load factor,diversity factor can be found.

Answer / shamsher singh

the maximum demand is the plant maximum load allow the state
electrical board on 500 kva we can use the load inside the
limit that in sanction load by the state electrical board
for a example our transformer is 500 kva and according
to power factor we calculate in standard 500*0.9=450kw .we
authorized only 450 kw only.govt authorized me only 450 kw
we cross the limit we pay the penalty
